TACTILE SENSOR

摘要

A tactile sensor is provided to reduce the size of a tactile sensor by decreasing the number of electrodes. A tactile sensor receives a tactile sensor select signal and a clock signal as one common signal. A signal separation part(120) receives the common signal to separate the common signal into the select signal and the clock signal. A unit device select switch(130) activates the tactile sensor according to the select signal. An output part(140) sequentially outputs piezoresistive signals of a plurality of piezoresistive detection elements through a common output terminal according to the clock signal. The output part can include a switch with respect to each piezoresistive detection element and a control unit for controlling the plurality of switches according to the clock signal. The tactile sensor can sequentially and serially outputs the piezoresistive signals.
