ELECTRIC DOOR RELEASE POWERED BY AN ENERGY HARVESTER

摘要

A piezoelectric energy harvester system for collecting kinetic energy is provided, wherein the kinetic energy is converted into electrical energy, and wherein at least a portion of the converted electrical energy is utilized to operate a load. The system comprises an energy input portion and an energy harvesting portion. The energy input portion includes an input member configured to be actionable by an outside force. The energy harvesting portion includes a capture member, a sprocket portion, and a piezoelectric energy harvester. The capture member is adapted for receiving mechanical input from the input member. The sprocket portion is disposed for movement with the capture member. The sprocket portion includes at least one radially disposed sprocket actuator configured for making contact with and exciting the piezoelectric energy harvester. The piezoelectric energy harvester is excited by the contact to produce the kinetic energy.
