Research Applications
- PVDF sheet can be used to prepare piezoelectric actuators. Compared with piezoelectric devices based on ceramics or single crystals, piezoelectric devices based on PVDF have the advantage of high flexibility. Piezoelectric polymer sheets usually have metal electrodes, which can significantly enhance the stiffness of the sheet and correspondingly reduce its piezoelectric response in actuator and sensor applications. The electrode of the conductive polymer poly(ethylenedioxythiophene) (PEDOT-PSS) is deposited on the PVDF sheet by spray gun and inkjet printing method.

- The PVDF sheet is prepared as a non-contact sensor sheet for sleep assessment. Each piezoelectric element is made of a PVDF sensor, which generates an electric potential when pressed or stretched in a certain direction. By measuring the resulting voltage change, the pressure can be estimated.
