Wireless charging in the car requires the installation of special equipment. Recently developed "nanogenerator" as it is called by the inventors, promises to greatly facilitate this task in the foreseeable future. This technology is suitable for integration directly into smartphones and tablets, delivering energy without the need of embedding special equipment in the car. The authors of the project are scientists from the University of Wisconsin in Madison, University of Minnesota Duluth and sun Yat-sen University.
A key element of the new development is the piezoelectric polymer polyvinylidene fluoride (PVDF). Like other materials of this group, the PVDF generates electricity as a result of mechanical impact. The process, which is based on a new technology, by introducing into the polymer substance of the nanoparticles of zinc oxide and their subsequent removal. The remaining PVDF in the thickness of the cavity gives it a porous structure and flexibility.
Formed according to this method the film is placed between two thin electrodes. The resulting plate has a small thickness and remains flexible and suitable for integration into devices of various shapes. The mechanical effect necessary for energy production, is the result of vibration of the vehicle.
