Patent ID: 7771846

Claim:
A high-permeability (L-L) configuration magnetostrictive/piezo-electric composite laminate comprising: a (1-3) piezo-fiber layer having piezo-electric fibers extending in a longitudinal direction; first and second high-permeability magnetostrictive alloy layers, the (1-3) piezo-fiber layer being laminated between the first and second high-permeability magnetostrictive alloy layers in an (L-L) configuration, wherein the magnetization axis of the first and second magnetostrictive alloy layers extends in the same longitudinal direction as the piezo-electric fibers forming the (1-3) piezo-fiber layer; and first and second thin polymer insulating layers, each with inter-digitated (ID) electrodes, placed between respective first and second high-permeability magnetostrictive alloy layers and the (1-3) piezo-fiber layer.
