CPC classification number: G01R33/0327 ,  G01R5/00

Abstract: A current sensor device. The current sensor device includes a strain distribution converter; an optical fiber coupled with the strain distribution converter; and a magnetostrictive material associated with the strain distribution converter such that a change in shape of the magnetostrictive material causes a change in length of the optical fiber.
