摘　　要：依据一种利用压阻特性的3×3点阵的柔性触觉传感器,设计了针对这种新型柔性触觉传感器的信号处理电路。该电路能完成信号放大、阵列信号的选通、A/D转换以及通过LED电路对其信号的采集。并详细地阐述了电路的原理和所用芯片的功能。所设计的信号处理电路能够判断出这种触觉传感器单元所受三维加载力的大小和位置。通过在正向压力的加载试验,验证了电路的可行性。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.
