A Wearable Wireless fNIRS System

Published: 18 January 2018 Publication History

Abstract

Neurovascular coupling mechanisms in functional brain activity has always been important areas of brain science. Functional near-infrared spectroscopy (fNIRS) has been utilized in the recent decades for examining functional brain activity by measuring the changes in the concentrations of oxygenated and deoxygenated hemoglobin. fNIRS is a noninvasive detecting technology, it has many characteristics such as high measurement speed, simple operation, fNIRS represents a good compromise in terms of spatial and temporal resolution, and so it's becoming more and more widely used. But recent fNIRS still non-wearable and participants are nonmoving.
In this work, we design a low-cost, low power, wearable and wireless fNIRS system. This system has two wavelengths light of 760nm and 850nm, and transfer data via Bluetooth. We design and make a plastic housing for fix the optical fiber by 3D printer. The battery can last several hours. In an experiment, this system can detect change of Hb and HbO2's concentration.
