ABSTRACT:
A strain gauge including: a system including a transmission coil, a magnetostrictive material layer and a receiver coil wherein an alternating transmission signal is applied across the transmission coil and an induced signal is induced in the receiver coil, the intensity of the detected signal across the receiver coil being a measurement of strain, wherein frequency of transmission signal is near to a resonance frequency of the system.
