Tactile Sensor and it's Signal Processing

This design accomplishes the task of installing touch and slide sensor on an artificial limb, which can realize the acquisition and conversion of both tactile and sliding signals. Besides it can also realize the sensory output. The sensor uses PVDF as sensitive material. The signal conditioning circuitry has the functions of signal amplification?filtering and signal acquisition. Signal acquisition and process circuitry solve the problems of separating tactile and sliding signals?judging threshold value and outputting the tactility and slide sensibility(switch signal). The pie-tail of the sensor and the signal conditioning circuitry designed for the sensor are placed inside the limb. It will not influence the normal action of the artificial hand's joint.
