PVDF based Piezoelectric (PZL) devices were fabricated to realize a very thin and simple bendable device to be integrated with the PMP layers. In this way the PMP / PZL structure, with the use of the copper foil, will be able to integrate easily and will be able to dissipate the heat more simply if the PMP is irradiated with high intensity light.
PZL devices fabrication:
- Active layer: bilayer (~ 7 μm) of PVDF + 10 wt% BaTiO3 deposited onto Copper foil (10 μm) by bar coating
- Top electrode: sprayed silver coated copper compound
