PVDF piezoelectric material is the piezoelectricity of the best organic polymer material found so far. It has the quality of a material soft, thin, light weight, high sensitivity, fast response, large measuring range, high chemical stability, low production cost, easy processing and processing, light weight, and many other performance advantages. After its discovery, since a lot of research and application, makes PVDF sensors become widely applied as a modern new smart sensor. In this paper， by using PVDF piezoelectric film excellent performance features， using ANSYS simulation software for numerical simulation analysis, and in accordance with the dimensional requirements of PVDF sensor mechanical parts to complete the structural design of the sensor. Then, according to the design size of PVDF sensor, carry on the drawing by using AutoCAD software. PVDF sensors perform physical production, and gives the PVDF sensor and assembly process. After completion of production, using the test device of the existing carries on the experiment, through the calibration of sensors, educes the corresponding experiment result and the performance characteristics. Finally, through the testing experiment on the designed sensor, test results accord with the design requirements, the designed PVDF sensor reliably available.
