Typical properties of piezo film. In this paper, a commercial polymeric piezoelectric film , the polyvinylidene fluoride ( PVDF ) was used to harvest electrical energy during the execution . As opposed to piezo -ceramics (i.e PZT), flexibility and robustness characterize piezoelectric polymers. We developed all polymer piezoelectric film which consists of PET substrate, conductive polymer electrode, polyvinilidene fluoride ( PVDF ) piezoelectric film in. PVDF sensing film was completely encapsulated within the sensor . PVDF film to generate the corresponding electrical signals.

To facilitate our customers who wish to purchase small quantities of piezo -electric polymers we stock a range of poled PVdF film. This can be supplied with or .
