Abstract
An oscillation sensing device includes a magnetised member mounted on a substrate. A magneto-electrical material is mounted on the substrate such that the magneto-electrical material is subjected to the magnetic field generated by the magnetised member. A movable member is mounted for oscillation in response to an oscillating force. Oscillation of the movable member causes a change in the magnetic field experienced by the magneto-electrical material and an electrical property of the electro-electrical material changes in response to changes in the magnetic field experienced by the magneto-electrical material due to oscillation of the movable member.
