针对目前触觉传感器研究中不能兼有柔韧性、多维力测量和热觉与触觉信号混杂等难题，设计了一种柔性多功能触觉/热觉传感器。介绍了该传感器的基本结构，并基于聚偏氟乙烯（ PVDF）薄膜的特性建立了三维力并行测量的数学模型。触觉检测基于PVDF的压电效应，热觉检测基于PVDF的热释电效应。通过对触觉和热觉信号做比例减法运算，从而彻底区分触觉和热觉信号。

Aiming at difficult problem that current tactile sensor can not have both flexible,multi-dimensional force measurement and thermal perception and tactile signals mixed,design a flexible multi-fumction tactile/thermal sensor. Introduce basic structure of the sensor,and set up mathematical model three-dimensional force parallel measurement based on polyvinylidene fluoride( PVDF )film properties. Tactile detection based on piezoelectric effect of PVDF and thermal detection based on pyroelectric effect of PVDF. Gy doing proportional subtraction on tactile and thermal sensing signal,completely distinguish tactile and thermal sensing signals.
