Description

<p>This paper describes the development of a several smart material devices such as stress-strain sensor and micro-energy harvesting based on our newly developed the robust magnetostrictive Fe-rich Co alloy. The principle of the “inverse magnetostrictive phenomena” and the basic design of ring-type torque-sensor are first mentioned and then, the magenetostrictive vibration energy harvesting those are characterized by leakage magnetic flux” associated by applied stresses is discussed.. These will become the important technique to develop the “IoT sensor net- work” devices in the near future.</p>
