摘　　要：研制一种可以感知触滑觉的传感器,该传感器由PVDF薄膜制作,因其柔顺的表面及小巧的尺寸使之能粘贴在手指上。信号处理电路对薄膜产生的微弱电荷信号进行转换、滤波、放大。软件程序采集并分离触滑觉信号,根据特征值的大小判断是否输出相应的感觉信息。A kind of sensor that could detect tactile and slip sense is developed. The sensor is made from PVDF film, and could adhere to fingers due to its complaisant surface and minimal size. Signal processing circuit completes conversion, filtering and amplification of electric signal from the film. Software samples the output signal of the circuit, and then analyses the characteristics of this signal to judge if generate corresponding sense information.
