Abstract

The gridless planar flexible sensors based on BP neural network have attracted wide interests in the design of smart sensing devices due to their high accuracy and low cost. In order to obtain the effective measurement data from the multichannel electrodes in a gridless planar sensor simultaneously, and to avoid the mutual crosstalk between the electrodes, a time-division multiplex piezoresistive measurement system based on serial port communication function is proposed in this work. A proportional amplification circuit is designed in this system to convert resistance signals into potential signals, and a STM32 is used as the main control chip to control two multiplexers to realize time-division multiplex transmission. The measured potential signals are converted by ADC and sent to computer with the help of USART. A PCB is designed and fabricated accordingly, and the fast and accurate multi-channel data synchronization acquisition is achieved.
