Abstract
The present invention relates to a force sensing device, and in particular to a force sensing device for sensing an oscillating force or for application as a filter. In general terms, the invention proposes a force sensing device having a magneto electric material and a magnetic element moveable relative thereto in response to an applied force. The magneto electric material is exposed to the magnetic field of the magnetic element which has a magnetisation direction parallel to the direction of the movement.
Claims10
A force sensing device having a magnetised element and a magneto electric material being each relatively moveable with respect to the other in response to an applied force, the magnetised element having a magnetisation direction parallel to the direction of said relative movement;
- the device being arranged such that said material is subject to the magnetic field of said element and such that an electrical property of said material which is indicative of said applied force varies dependent said relative movement.
