BROADBAND PIEZOELECTRIC ENERGY HARVESTER USING M TYPE BEAM

摘要

In the broadband piezoelectric energy harvester using an M-shaped beam according to an embodiment of the present invention, a main beam having one end fixed to a fixed end and vibrating, is located spaced apart from both sides of the main beam, and one end is the same line as the end of the main beam. A sub-beam connected to the top and vibrating, a piezoelectric member formed on one surface of the main beam and the sub-beam, generating electric energy by vibration of each beam, and provided to face each other at the other end of the sub-beam and the fixed end It includes a magnetic substance that becomes.
