A wearable, wireless electronic interface for textile sensors lin shu

Electronic interfaces for wearable sensors require wireless connection, appropriate measurement range, small size, simple and robust structure, insensitivity to noise and comfort to wearers in daily life. A novel wearable, wireless electronic interface for resistive textile sensors is presented, which meets the requirements and has the ability to provide real-time measurement. System configuration, accuracy and resolution have been analyzed in-depth and design rules have been defined. Experimental results show that this electronic interface exhibits less than 1% error in a large measurement range for wearable textile resistive sensors. It also shows a good stability to power supply interference. The interface has been successfully applied in a foot pressure measurement system.
