Piezoelectric Energy Harvester using inertia force in the train

摘要

A piezoelectric power generation device according to an embodiment of the present invention includes a support having one end fixed to the inside of a moving body and a piezoelectric element attached to one side thereof and an inertial member attached to the other end of the support to generate acceleration or deceleration And an application unit including at least one of a storage device, a rectifier device, and a load device capable of changing the weight generated by the piezoelectric device to a desired application, an inertia force due to shaking of the moving object, .
