摘要：
A torque sensor based on the Villari effect. The sensor uses high frequency alternating magnetic fields and the Villari effect to determine the state of stress/strain inside a magnetostrictive shaft for the purpose of measuring torque. The invention teaches design elements for the sensor and shaft; namely, the desirable magnetic, electric and structural properties for various elements of the sensor.
