NONLINEAR VIBRATION ENERGY HARVESTING SYSTEM

摘要

A system for harvesting energy from mechanical motion and/or vibrations is disclosed. The system incorporates a nonlinear double pendulum mechanism. The nonlinear mechanism can be mounted on a frame that is fixed to a moving or vibrating object. A transducer can be coupled to the frame and/or the nonlinear mechanism in order to convert the relative motion of the frame and the nonlinear mechanism into electrical energy or stored mechanical energy. The recovered energy can be used to provide primary or supplementary power to certain electronic and mechanical devices.
