Title: AN ENERGY HARVESTER AND A SYSTEM USING THE ENERGY HARVESTER
Abstract:
An apparatus comprises a membrane having a planar surface enclosed inside a duct structure which has an opening provided at an end thereof. A permanent magnet fixed to the membrane is configured to oscillate in response to a mechanical disturbance caused by a vibrating fluid within the duct structure. The oscillation of the membrane causes the permanent magnet to move inside an electromagnetic coil to thereby induce electric energy in the coil. An energy harvester and a system for monitoring a condition of an object are also disclosed.
