PIEZOELECTRIC ENERGY HARVESTING DEVICE USING CURVED ELASTIC PLATE

摘要

A generator module and a piezoelectric energy collecting device are provided to amplify the action of objects through a film-type piezoelectric element and a curved elastic plate and collect it to produce electricity. A generator module comprises a first inertia block attached to an object, a second inertia block working as a mass in a vibration system, a curved elastic plate(2) whose both ends are connected to the first and second inertia blocks(1), and a piezoelectric film(3) attached to one or both of the sides of the curved elastic plate. The curved elastic plates are located between the first and second inertia blocks so that the curved side faces outside.
