Abstract

Aiming at the present situation that domestic polyvinylidene fluoride（PVDF） piezoelectric sensor only is restricted in the laboratory stage

massive imports are still needed.The preparation technology of PVDF piezoelectric sensor is studied by analyzing the piezoelectric characteristics of PVDF and combining the structure of sensor products.The preparation process parameters of the main processes such as initial film preparation

uniaxial tensile

high pressure polarization and magnetron sputtering in the process are explored.Sensitive PVDF piezoelectric film is obtained and polyimide materials are used for packaging

PVDF piezoelectric sensor is achieved.Key parameters of the sensor

static piezoelectric coefficient d

is test

the results is 13 PC/N.PVDF pi

ezoelectric sensor products satisfied practical engineering is obtained.
