ABSTRACT:
A magnetoplastic and/or magnetoelastic material transduces linear motion, delivered to it by a mechanical connection, into a change of magnetic field, via twin boundary deformation. A bias magnetic field assures a net change of magnetization during the deformation, and a coil, coaxial with the magnetoplastic/elastic material, couples the magnetic field change to an electrical output. The bias magnetic field or a device that produces strain in a reverse direction resets the magnetomechanical transducer to its initial state. Microgenerators using the magnetoplastic/elastic material may be connected in series or parallel, combined with solar cells, and used to capture energy from passive motion such as random, cyclic or vibrational motion.
