Problems solved by technology

[0002] At present, as a dynamic strain sensor, the piezoelectric thin film sensor is suitable for implanting on the surface of the human skin or inside the human body to monitor life signals. In the prior art, the preparation of the piezoelectric thin film sensor needs to be relatively Holes are set on the front surface and the back surface, and the holes are penetrated to the front surface and the back surface. However, during this process, due to the certain elasticity of the PET film, when the PET film is opened, In the case of eccentricity, and after the opening is completed, burrs remain on the front and back surface of the PET film at the edge of the opening, as well as the residual PET film bonded, which causes the outer surface of the PET film to be uneven, thereby greatly reducing the The monitoring performance of the piezoelectric film sensor

Abstract

The invention relates to the field of sensors, in particular to a matrix type hole forming machine for a PET film of a piezoelectric film sensor, and aims to provide a matrix type hole forming machine for a PET film of a piezoelectric film sensor. According to the technical scheme, the matrix type hole forming machine for the PET film of the piezoelectric film sensor comprises a bottom plate assembly, supporting legs and the like; and the four corners of the lower portion of the bottom plate assembly are each fixedly connected with one supporting leg. According to the matrix type hole forming machine, the PET film is limited, the two ends of the PET film are tensioned, so that the PET film is in a tightened state, then holes are formed in the PET film, burrs at the hole-formed edge of the front face of the PET film are removed, burrs at the hole-formed edge of the back face of the PET film are removed, then the PET film is cut off, the cut-off PET film is collected, the eccentric condition is avoided, the outer surface of the PET film is smooth, and the monitoring performance of the piezoelectric film sensor is greatly improved.
