Force sensing device
First Claim
1. A force sensing device comprises a magnetised member mounted on a substrate, a magneto-electrical material mounted on the substrate such that the magneto-electrical material is subjected to the magnetic field generated by the magnetised member, a movable member mounted for movement in response to an applied force, movement of the movable member causing a change in the magnetic field experienced by the magneto-electrical material, and an electrical property of the magneto-electrical material changing in response to changes in the magnetic field experienced by the magneto-electrical material due to movement of the movable member.

Abstract
An oscillation sensing device (1) includes a magnetized member (6) mounted on a substrate (4). A magneto-electrical material (7) is mounted on the substrate (4) such that the magneto-electrical material (7) is subjected to the magnetic field generated by the magnetized member (6). A movable member (3) is mounted for oscillation (8) in response to an oscillating force. Oscillation of the movable member (3) causes a change in the magnetic field experienced by the magneto-electrical material (7) and an electrical property of the magneto-electrical material (7) changes in response to changes in the magnetic field experienced by the magneto-electrical material (7) due to oscillation of the movable member (3).
