Wireless biomechanical power harvesting via flexible magnetostrictive ribbons

Abstract

Magnetostrictive Terfenol-D ribbons exhibiting superior magnetization values were printed onto a silicone elastomer. Deformation of the magnetostrictive ribbons alters domain orientation, which changes the magnetic flux. Interfacing the flexible magnetostrictive ribbons with a biomechanical source led to continuous sample deformations, which resulted in ‘radiating’ electromagnetic power to a remote receiver, thereby realizing wireless biomechanical power harvesting.
