BACKGROUND OF THE INVENTION

Nowadays, clothing is no longer considered only as a piece of man's clothing that only protects and beautifies it, but also as an intelligent device. Clothing can recognize the temperature of the environment, illuminate, monitor the vital functions of a person, or can change colors and patterns. This is made possible by new textile fibers and fabrics made therefrom which are capable of responding to external stimuli by incorporating electronic devices or intelligent materials therein. Depending on the technology of intelligent fabric creation, they can be divided into:

• heat sensitive fabrics, • luminescent fabrics, • with wind-sensitive fabrics, • e-fabrics.

Heat-sensitive textiles are made by adding a heat-sensitive pigment, changing their color based on ambient temperature. This process is reversible. By adding shape memory materials, they use a thermoelectric phenomenon and, in combination with textiles, offer a solution for measuring the temperature of clothing. By admixing small wax microcapsules, they absorb heat during physical exertion and then recover it again. Their use is mainly in medicine, for example to measure the temperature of the patient and the like, in fashion as clothing with changing colors of printing, self-ironing fabrics for the clothing industry, or interior design.

Luminescent fabrics are made by adding pigments to textile synthetic fibers that are capable of emitting light in the dark. They are used mainly as protective equipment in the fashion industry, eventually. as active camouflage for military purposes.

Na ssensitive fabrics change color depending on the intensity of sunlight. They are especially useful in measuring UV intensity, in the fashion industry and interior design.

E-fabrics behave like electronic devices, i. j. they can conduct electrical current. They can be connected to other devices, such as an LED bulb, communicate with smart phones, or transmit heat. Most often they contain metal fibers. They are used especially for complete monitoring of the human body for military, medical or sports purposes. They can find out what substances are missing in the body. It is known intelligent shirt containing embedded sensors that constantly gather information about various cardiopulmonary parameters.

Several projects for the preparation of smart textiles and garments already exist or are under development, such as:

1. A program of smart textiles and clothing bearing the Biotex label, designed to supervise the health of the owner. Sensors placed in the fabric collect information about the amount of acids and salts from the sweat. Based on this information, a report on the health of the organism will be drawn up. Within the European MyHeart project, the emergence of bed linen that can provide pulse, ECG and respiratory activity information using pressure-sensitive biosensors. Similar sensors can also be placed on clothing worn directly on the body. The information is then wirelessly transmitted and displayed to a mobile device similar to a mobile phone.

2. Textile prototype marked GTWM under the trade name inteUgentná košile is designed for military purposes. Such a shirt uses optical fibers to detect wounds with special detectors monitoring the wearer's health. A flexible control board with medical detectors is integrated directly into the shirt. GTWM textile e-system is a fabric made of polymer optical fibers and other special intelligent threads that form an integrated e-textile. The shirt may contain several kinds of detectors, for example sensors for detecting oxygen or other hazardous gases. Other sensors monitor breathing rate, body temperature, and more. InteUgent Shirts, such as the SensaTex trade name, are used for commercial purposes, for medical disease monitoring, for monitoring infants, athletes, and for military purposes.

3. Smart Fabrics is a new material that can track physiological manifestations. This technology is based on sensors arrested in clothing. They can collect and transmit physiological data such as life or other biomechanical information in real time. These sensors are capable of detecting and measuring pressure, force, deformation and various other relevant data. Sensors can collect information regarding heart rate, temperature, posture, respiratory rate and electrocardiogram (ECG). Detected in2

With K 8218 Y1 the formations can then be stored or sent to the central office. The product named BioHames s is a lightweight belt that can be worn around the chest. Measures biological data when performing an activity. It can monitor heart rate, respiratory rate, skin temperature, posture, activity level, maximum acceleration, space movement, approximate respiratory amplitude, and approximate ECG.

Intelligent garments are a group of garments that are capable of sensing at least one human biological signal induced by the life manifestation of the organism. The basic functional element of intelligent garments are electrodes, which may be of textile or non-textile nature, whose role is to sense biological signals from the surface of the human body. Functionality of electrodes is ensured by their conductive properties, which can be achieved with textile electrodes:

- using length, resp. flat electrically conductive textile materials (fibers, yarns, fabrics, knitwear, etc.),

- applying electrically conductive particles to the surface of the fabric, e.g. printing technology;

- application of other electrically conductive materials such as. silicone, gel and the like.

In terms of the method of sensing a biological signal, the textile electrodes may be passive or active. The textile electrodes can be integrated into the garment structure by sewing, knitting, embroidery, removable, or form a fixed part of the garment. The design, shape, number and placement of electrodes in the garment depends on the type of sensed biological signal (bioelectric, biomechanical, etc.). The interconnection of the sensing electrodes with the electronic elements is, for example, a control and communication unit, and the electronic elements, which are part of each other in an intelligent garment, provide electrically conductive paths that fulfill the function of data and power conductors intended to transmit sensed signals. Conducting paths can create:

- electric wires which may be fixed or removable parts of intelligent clothing,

- electrically conductive textile elements integrated directly into the structure of the carrier material of the smart garment by a technology of knitting or weaving by an electrically conductive yarn, possibly formed on the surface of the carrier material by an embroidery technology by an electrically conductive sewing thread.

The design, shape, number and placement of conductive paths in smart clothing depend on the conductive path function (power, data) and the layout of the other functional elements of the garment. The electronic portion of the smart clothing may consist of one, two or more separate units (e.g., control, communication, and the like), which are electrically connected to one another by conductive paths. They consist of electrical circuits with integrated electrical components. The composition of the electronic components of the smart garment is designed to ensure the transmission of the scanned biological signals in the desired quality via wired or wireless communication to the evaluation unit. They can be removable or an integral part of smart clothing. Available applications and / or applications are used to collect, process, evaluate, display and archive biological data. Apps tailored to smart clothing.

According to patent EP 2845538 A1, a garment with a set of textile electrodes placed on a garment with a contact and a non-contact electrode is known, wherein the set of textile electrodes is placed on a garment with a lowered element to reduce movement artifacts. In certain cases, the set of be / contact textile electrodes may be inserted and used in a pocket for electrode placement or in a tunnel designed for clothing. The electrode array of the present invention can detect various kinds of biosignals, such as heart activity, ECG signal, EMG signal, respiratory signal and the like. The invention relates only to obtaining information from a set of electrodes and to a method for positioning them, but does not include the way in which the biological data collected by it is processed and evaluated. However, such a solution is technically and functionally complicated for the user, unnecessarily expensive, and uncomfortable for the user.

According to US 20080208029 A1, a garment comprising at least one dry electrode is known. It is an object of the invention to provide a monitoring system suitable for home use. The formed garment comprises at least one dry electrode used with a monitoring system to monitor human physiological parameters. According to the invention, the position of the electrodes on the body has an influence on the quality of the signal obtained, wherein the dry electrodes are mounted at clothing points in which close contact with the human body is automatically ensured and a natural layer of sweat is present with the clothing worn. Since a natural sweat layer is present around the armpit, the functionality of the electrode is automatic when it is located in the armpit region. A drawback of this solution is the need for the presence of a layer of human natural sweat to provide better conductivity due to a weak biological signal.

According to US 20070073131 A1, clothing for measuring physiological signal is also known. Such clothing comprises: an inner layer formed of an elastic mesh fabric; electrodes for measuring a physiological signal, including a connector connected to an external line, and electrodes having a protrusion and measuring a physiological signal, wherein the protrusion of the electrode passes through the inner layer mesh and connects to a connector that is connectable to the inner layer. A compressible pad, which is sandwiched between the outer and inner layers, presses the electrode to measure the physiological signal to the human body. In this way, the lack of contact between the electrode for measuring the physiological signal and the human body in reducing noise is avoided.

S K 8218 Y1 generated during measurement of the physiological signal. However, its disadvantage is the technical limitation that such clothing is connected only to an external line without its own evaluation device, and is too complex, costly and user-friendly.

According to U.S. Pat. No. 20100234715, a garment for measuring physiological signals and a method for its production is known. Such a garment is designed to measure physiological signals and comprises at least one electrode sensor, a signal connection cable, connecting the structure and the measuring unit. The electrode sensor is connected to the inner surface of the garment so as to be in contact with the skin to allow the detection of physiological signals. The connection line transmits physiological signals detected by the electrode sensor and the signal connection is terminated on the inner surface of the garment. The bonding structure is connected to the garment at a point where there is no electrode overlap and is electrically connected to the signal connection. The measuring unit is installed on a connecting structure for measuring physiological signals. The signal connection is elastic. The disadvantage of the solution is that such a garment does not have formed textile connecting paths, requires special expensive maintenance and is intended only for measuring physiological signals without its own evaluation device.

Also known in the US patent 9566033 B2 is a suit system with electronic components and associated methods. The solution provides a wireless biometric monitoring system that has the ability to acquire, analyze, and transmit biometric data in real time. The system can use either the most current bluetooth protocol (currently Bluetooth Smart) or a similar wireless protocol. The system can be further integrated via said wireless protocol with peripheral devices to expand the measurement capacity of the system. When deployed, the system can monitor several biometric signals, i. j. skin temperature, body temperature, breathing, heart rate, predicted tidal volume, chest wall movement, abdominal movement related to inhalation, HRR (heart rate reserve), HRV (heart rate variability), body position relative to perpendicular, shoulder position relative to hip area, upright time, recumbent time, and disturbances. The disadvantages of such a solution are that they do not form part of a complex human clothing system, the absence of textile connecting paths, the absence of a mobile application to display and analyze the scanned data, the structural complexity and cost of the clothing system.

US 2013/0041272 A1 also discloses a garment embedded sensory device comprising one or more sensors, one or more fasteners to which an electronic device for receiving data from a sensor or multiple sensors, a first textile layer may be attached which is in use on the inner part of the garment, a second textile layer which is in use on the outside of the garment during use, and a third intermediate layer formed between the first and second layers at least along a portion of said tube, said first and second textile layers being produced in particular and the third intermediate layer is substantially stiffer than the first and second textile layers. The sensors may be ECG and respiratory sensors. The disadvantage of such a solution is that it relates only to the sensory device applied to the garment without its own evaluation device and that it does not form part of a complex human clothing system, thereby making it less comfortable for the user.

According to US 20110004088 A1, an ECG elastic shirt is known which creates a safer skin bond and a more accurate and standardized placement of ECG electrodes in men, women and children. The ECG T-shirt reduces unexpected movements or dislocations. Such a T-shirt allows the use of most ECG devices with different types of electrodes, facilitating the implementation of not only twelve lead rest ECG, but also testing during exercise and monitoring fifteen lead and two different types of eighteen lead ECG test. ECG T-Shirt is a tool for teaching expert placement of ECG electrodes. The disadvantage of such a T-shirt is that it only serves to place external ECG electrodes, i. i.e. that it does not contain its own textile electrodes with textile conductive paths (interconnections), it requires special costly maintenance and complicated ECG measurement system evaluation, making it less user-friendly.

The essence of the technical solution

These deficiencies are largely eliminated by intelligent clothing for monitoring human biodata, in particular an electrocardiogram signal composed of clothing, conductive fibers, passive contact textile ECG electrodes and at least one outlet to an electronic device. The essence of the invention is that the garment structure comprises insulated electrically conductive fibers from the outside of the human body connecting its passive, contact textile electrically conductive ECG electrodes and the contact textile ground electrode to at least one electrical signal outlet for the electronic device.

It is advantageous here that the electronic device consists of a control unit and a communication unit, which are electrically connected to each other.

S K 8218

Furthermore, it is advantageous if the communication unit of the electronic device is connected to the electrical outputs of the control unit and is formed by a charging controller which is electrically connected from one side to an internal power supply electrically connected in parallel to the first voltage converter DClDC of the control unit and via a second DC / DC converter DC with a biometric data transmitting module and, on the other hand, via an external terminal with an external power source, the transmitter module being connected wirelessly and / or at least one external terminal to an external evaluation device of the electronic device.

At the same time, it is advantageous if the electrical signal terminals are removably connected to the electronic device and the supply of the first DC / DC voltage converter and the electrical connection of the controller and the communication module of the communication unit are removably connected via the electrical signal outputs to the communication unit.

It is further preferred that the control unit is mounted in a watertight package in a garment structure and rigidly connected by electrical signal outlets to the communication unit.

At the same time, it is advantageous if the control unit is mounted in a waterproof package in the garment structure and is firmly connected to the electrical signal terminals and the electrical signal outputs of the removable communication unit.

At the same time, it is advantageous if the passive electrically conductive ECG electrodes and the contact textile ground electrode are prepared from a knit of electrically conductive fibers integrated into the garment by sewing with an electrically conductive sewing thread in which the electrically conductive yarn is embedded.

It is further preferred that the passive electrically conductive ECG electrodes and the contact textile ground electrode are integrated into the garment by direct embroidery by an electrically conductive sewing thread.

It is likewise advantageous if the conductive fibers are integrated into the garment by direct embroidery by means of an electrically conductive sewing thread.

Intelligent clothing for monitoring human biodate, especially the ECG signal according to the invention, enables the user to make technically simple, low-cost and reliable measurements of human vital functions by using textile electrodes integrated into the garment, as an alternative to the previously used costly Ag / AgCl electrodes. An important advantage of the technical solution is that its textile electrodes function as dry electrodes while allowing reliable ECG signal measurement without the use of an electrolyte gel or adhesives. Another big advantage of such a technical solution is that it utilizes the connection of textile fibers and materials, electronic part and mobile application into one simple blown, systemically interconnected unit designed for non-invasive monitoring of human bioelectric signal and enables complete processing and archiving of scanned ECG signal with simple permanently ensuring routine maintenance of such clothing during use. The technical solution also enables affordable permanent monitoring of the health condition of older people, primarily aimed at simplifying health care and raising its outpatient lumina to a qualitatively higher level by overcoming the limitations of outpatient technology and responding quickly to the need for real monitoring of human health. Such remote monitoring of human physiological parameters is suitable and advantageous especially for post-operative conditions, patients suffering from chronic diseases, patients with heart disease, but also for preventive health monitoring, disease prevention, rehabilitation and sports medicine. The technical solution also enables preventive health care for cardiac patients and at-risk groups of children who are at increased risk of Sudden Infant Death Syndrome (SIDS), as well as health care for active athletes in the form of continuous monitoring of their ECG during normal everyday activity or training or performance using systems that do not need to be wired. The intelligent ECG monitoring apparel of the present invention has a number of other benefits as textile electrodes and electrically conductive paths are integrated into the garment, thereby ensuring the comfort and comfort of the wearer while not restricting the mobility of the monitored person. Another great advantage of the technical solution is that during measurement the user does not perceive monitoring as the data is collected without his knowledge and that it allows the measured physiological signal from the carrier to be easily sent to the smart device or to the alert in real time. real time and any time. An important advantage of this technical solution is also its suitability for use in the health care of households or people in places far from the medical facility.

EXAMPLES

Example 1

This example relates to the basic variant of intelligent clothing for monitoring human biodate, especially the electrocardiogram signal according to the technical solution shown in FIG. 1 and FIG. 2. The support part of the garment 8 is formed by a sleeveless t-shirt made mainly of conventional elastic non-conductive knit. The front portion of the T-shirt is comprised of an outer portion and an inner portion not shown, on which functional textile elements are placed, i. j. two passive contact textile ECG electrodes 41, a contact textile ground electrode 42 and their conductive conductive fiber paths 7 terminated by a first portion of terminals 43, for example, contact textile metal fasteners in the form of conventional metal detachable rivet buttons for joining garments 8. The electronic device 3 is formed by a control device. It is located in a position between the passive contact textile ECG electrodes 41 and the contact textile ground electrode 42, being detachable therefrom during the maintenance of the garment 8 and fitted in a protective sleeve with a second portion of terminals 43, for example contact textile metal fasteners. in the form of conventional metal removable rivet buttons for joining garments fastened to a protective case, preferably of plastic.

In this case, the control unit 1 and the communication unit 2 are electrically connected to one another via three or four electrically conductive textile paths. Two conductive paths are used to communicate the controller 11 with the transmitter module 21, for example via a UART interface or the like. and the remaining or the other two conducting paths for connecting an internal power supply 23, e.g. 500 mAh LiPol batteries, allowing continuous ECG signaling for more than 80 hours, to the first DC / DC converter 13. However, in standby mode, the device lasts up to approximately 380 hours, while the charge controller 24 allows the internal power supply 23 to be charged through the external outlet 25 from the external power supply 6 and the discharged internal power supply 23 not shown. , for example, a microUSB connector or a connector from a conventional mobile phone charger, etc., wherein the charging, full charge, and discharge status of the internal power supply 23 are indicated by LEDs (not shown). The control unit 1 provides sensing and digitization of a single-channel ECG signal, which is controlled by a controller 11 adjusting the desired parameters and at the same time mediating communication with a transmitter module 21, for example a bluetooth module and the like. The electronic device 3 is mounted on the front side of the top of the front garment 8 and is provided with a second portion of contact textile metal fasteners, for example conventional metal detachable riveting buttons for joining clothes, connectable to detachable terminals 43 of passive contact ECG electrode 41 and contact textile ground electrodes 42, which are insulated with conductive textile connections on the face side of the inner layer of the front garment 8, which is in direct contact with the skin of the person being monitored. The passive contact textile ECG electrodes 41 and the contact textile ground electrode 42 are sensitive sensors of the electrical activity of the heart generated by the human body and are located below the human breast line, on the right and left side of the armpit. For this reason, the contact textile ground electrode 42 is located in the center of the abdominal region to obscure the frequency of 50 Hz (line noise) and to eliminate the interference of surrounding signals. Human electrocardiographic signal (ECG) sensing is from the contact textile ECG electrodes 41 and the contact textile ground electrode 42 via the conductive fibers 7 integrated into the garment 8 and an externally centrally mounted electronic device 3 transmitted by a transmitter module 21, for example Bluetooth wireless technology or the like. external terminals 25, such as a tablet, a mobile phone, to display and analyze the scanned data using special software to measure the biological data of an electrocardiogram based on an intelligent fabric that is in direct contact with the human body and which it sends control codes to the communication channel, receives the measured data, displays it on the display, and stores it on the internal storage depending on the user interaction. The measured data are electrical biosignals measured on the leads of an intelligent fabric, and such an application also displays the electrocardiogram of the measured person, if necessary. The advantage of this application software is that the data can be viewed repeatedly or the recording can be started in real time, even in the form of a simulation of the original measurement. The solution also provides the ability to create additional applications from existing modules in order to adapt them to user requirements and independently analyze measured data using existing tools.
