Piezoelectric–electromagnetic integrated vibrational hybrid energy harvester for low power applications
https://orcid.org/http://orcid.org/0000-0003-2922-3454
In this paper, we proposed an electromagnetic-piezoelectric integrated vibration based energy harvester to scavenge energy and generate steady power. By adopting rectangular cut cantilever with rectangular portion comprising the PE section and remaining cut portion acts as proof mass and NdFeB magnet which is surrounded by the coil. Power is harvested simultaneously by means of electromagnetic induction and piezoelectric principle. Though it works on different mechanisms, the design and fabrication of the harvester is as simple as the device with single energy conversion process, which results in reduced size and attains a greater power density. The design of hybrid harvester was modeled and investigated by using COMSOL multi-physics which produces 120 μW at its matching frequency with an optimum load.
