The polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) piezoelectric film was obtained by the in-situ polarization, which 10x increased the piezoelectric coefficient d33. By using our polarizing system, the PVDF-TrFE film can be polarized in 5 minutes at room temperature. Compared with the traditional polarization method, the in-situ polarization was performed with low poling voltage, short poling time, and can ensure the obtained PVDF-TrFE film with enhanced piezoelectric performances and uniform distribution among large area. The results provide a new method for PVDF-TrFE films with large area and high piezoelectric coefficient, which improves the piezoelectric performance and broadens the application in energy harvesting.
