Harvesting Electricity from Vibrations
In the new study, researchers have designed one using thermoplastic polyurethanes (TPU) and Polyethylene terephthalate (PET) as tribo layers. The easy availability of the active material and the simplicity of the fabrication process make it cost-effective over currently available fabrication techniques. The resulting device has also been found to be highly efficient, robust, and gives reproducible output over long hours of operation.
