A piezoelectric sensor is used for the pulse signal of a body, which is generated by the signal generated by the internal pulse of the pulse receiving medium. Other effects produced by the lifting of force in this paper refer to the phenomenon that piezoelectric can extract the human body (including bending and stretching deformation) under the action of external force in a certain direction of some dielectrics. When this kind of deformation occurs, the charge will extract the human image, and the phenomenon will occur in its electric charge.
