Research on sensing characteristics of PVDF piezoelectric film and its application in aerospace static test

PVDF (Polyvinylidene fluoride) as a new type of piezoelectric material, it has advantages incomparable to other materials in piezoelectric performance and physical materials. This paper introduces the characteristics and principle of piezoelectric film and its application in various fields at home and abroad. In view of situation of complex structure and difficult measurement of space vehicles, a static test and measurement system based on PVDF piezoelectric film sensor is designed. Finally, defects of piezoelectric film in application and future development direction are discussed.
