The smart graphene-PVDF electrical response film developed by this technology induces PVDF self-assembly arrangement through graphene. It does not need to go through the polarization process to have piezoelectric characteristics, and use the high conductivity of graphene itself. And the electric energy signal generated after the mechanical energy is activated can be collected without installing electrodes. It greatly simplifies the preparation steps of the piezoelectric thin film, and due to the characteristics of not requiring polarization, it can be directly coated on materials with different curved shapes and directly cured to form a piezoelectric sensor.The smart graphene-PVDF electrical response film developed by this technology induces PVDF self-assembly arrangement through graphene.

Or it can be made into a thin film and applied to the wave power generation, so that a single film can obtain drinking water and generate electricity at the same time.
