Based on the high performance of newly developed magnetostrictive FeCo71at% alloy (2011), we have developed two types of smart stress sensor devices, i.e. 1) stress/strain sensor for the machinery and infrastructure by measuring Barkhausen noise using FeCo fine wire, and 2) torque-sensor by measuring the leakage magnetic flux from the edge of magnetostrictive FeCo ring attached on the rotational shaft. The developed torque-sensor unit was applied to electric motor assisted system of spin-bike. These sensor application technologies will be enhanced by combining IoT wireless sensor net-work for Industry 4.0 or Society 5.0 in the near future.
