Abstract

Based on the use of piezoresistive effect of a 3×3 matrix of flexible tactile sensor

a new signal processing circuit is designed.The circuit can fulfill requirement as follows:signal amplification

choosing signal from sensor array

A/D conversion and collecting signal by LED circuit.And the principle and the circuit chip with the function are detailed.The signal processing circuit designed can determine which suffered three-dimensional tactile sensor unit load size and position of power.Through the loading experiment at positive pressure

the feasibility of the circuit is verified.
