Description
Technical field
This utility model relates to a kind of Graphene urine sensor.
Background technology
The disposable absorbent articles such as diaper, training pants, incontinence pad can effectively make wearer away from humidity, reduce by
The skin allergy caused in the moistening exposure extended.But, because these article absorbabilitys are very strong, wearer may not
Can be appreciated that they have pissed, such as infant, old man etc..Wearer may be unaware that its piss control unsuccessfully or
Do not recognize that wear should be changed.Additionally, parents or caregiver are also possible to will not find the one of wearer in time
Secondary property absorbent commodity needs to change.Therefore, it is possible to the sensor perceiving urine existence just arises at the historic moment.
At present, existed some can perceive urine exist sensors, such as based on electronics Wetness sensors,
Wetness sensors based on color and Wetness sensors based on enzyme etc..But, the usual structure of these sensors is complicated, valency
Money is expensive, and the signal that these sensors produce the most all can only exist relatively short period of time.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, low cost, the Graphene urine of induced signal persistent period length
Liquid sensor.
The technical scheme realizing this utility model purpose is: a kind of Graphene urine sensor, including base material, setting
Graphene inductive layer, the colloidal materials being arranged on Graphene inductive layer on base material, it is arranged on colloidal materials
Can pass through the protective layer of solution, two electrodes being connected with Graphene inductive layer two ends respectively and respectively with two
Two electrode outlet lines that electrode connects；Urine sensing hole it is reserved with on described colloidal materials；Described urine sensing hole is upper
Under the through hole that runs through.
The material of described protective layer is non-woven fabrics or stationery or plastic wire or elastomeric material or textile
Fabric.
Described electrode is metal or organic conductive material or material with carbon element electrode.
Described urine sensing hole is one or more hole, or is by a group pattern hole of geometric arrangements.
Have employed technique scheme, this utility model has following beneficial effect: this utility model utilizes in urine
Graphene is played chanza by effective ingredient carbamide, makes the carrier concentration of Graphene increase, so that the leading of Graphene
Electricity rate improves, and peripheral test circuit can be determined whether in time by the resistance variations between two electrode outlet lines of detection
Urine exists, and has a simple in construction, low cost, the advantage of induced signal persistent period length, and permissible after over cleaning
Reuse 1～5 time.
Accompanying drawing explanation
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine accompanying drawing,
This utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Being numbered in accompanying drawing:
Base material 1, Graphene inductive layer 2, colloidal materials 3, protective layer 4, electrode 5, urine sensing hole 6.
Detailed description of the invention
(embodiment 1)
See Fig. 1, the Graphene urine sensor of the present embodiment, including base material 1, it is arranged on base material 1
Graphene inductive layer 2, the colloidal materials 3 being arranged on Graphene inductive layer 2, be arranged on colloidal materials 3 permissible
Through the protective layer 4 of solution, two electrodes 5 being connected with Graphene inductive layer 2 two ends respectively and respectively with two
Two electrode outlet lines that electrode 5 connects.
Urine sensing hole 6 it is reserved with on colloidal materials 3.Urine sensing hole 6 is the through hole run through up and down.Urine sensing hole
6 is one or more hole, or is by a group pattern hole of geometric arrangements.The material of protective layer 4 be non-woven fabrics,
Or stationery or plastic wire or elastomeric material or textile fabric.Electrode 5 is for metal or organic leads
Electric material or material with carbon element electrode.
The principle of the Graphene urine sensor of the present embodiment is: urine is by flowing into glue through the protective layer 4 of solution
In urine sensing hole 6 on body material 3, thus touch Graphene inductive layer 2, the effective ingredient carbamide pair in urine
Graphene plays chanza, makes the carrier concentration of Graphene increase, so that the conductivity of Graphene improves.Peripheral
Test circuit by detection two electrode outlet lines between resistance variations can obtain urine to Graphene doping not
With the resistance variations caused.Generally use constant voltage to measure electric current or voltage is measured in constant current, or use square-wave signal voltage to press
Resistance variations measured by certain rate of scanning.
The resistance sensitivity of the Graphene urine sensor of the present embodiment is that <urea content of 0.001%, the urine of ordinary person can
To cause the change of the resistance 5%～200% of the Graphene urine sensor of the present embodiment.And the Graphene of the present embodiment
Urine sensor can be reused 1～5 time after over cleaning.
The Graphene urine sensor of the present embodiment is applicable to the diaper of baby, adult and old man, can quickly detect
Amount of urine, and by peripheral circuit sending out signals.
Particular embodiments described above, has been carried out the purpose of this utility model, technical scheme and beneficial effect further
Describe in detail, be it should be understood that and the foregoing is only specific embodiment of the utility model, be not limited to
This utility model, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done,
Within should be included in protection domain of the present utility model.
