Title:
MAGNETOMECHANICAL TRANSDUCER, AND APPARATUS AND METHODS OF HARVESTING ENERGY
Document Type and Number:
WIPO Patent Application WO2008049124
Kind Code:
B1
Abstract:
A magnetomechanical transducer, and apparatus and methods using said magnetomechanical transducer, extract electrical power from any motion, including random motion, cyclic, and vibrational motion. The motion is transferred to linear motion through a mechanical connecting device to the magnetomechanical coupler, which comprises a magnetoplastic and/or magnetoelastic material that transduces the linear motion into a change of magnetic field, via twin boundary deformation. A further transducer, couples the magnetic field change to an electrical output. A restoring field or device resets the magnetomechanical transducer to its initial state.
