Abstract
A force transducer element () comprises a body () of magnetisable material having at least one magnetised region () at an angle, say 45°, to the force-sensing direction (P—P). Preferably there are a plurality of parallel magnetised regions of alternating opposite polarity of magnetisation to form closed loops (). The element may be a block having opposite force receiving surfaces ('). The body () may contain plural transducer elements () angled to one another to resolve force directions. The principle is extended to a circular transducer element (). The invention may be implemented in a flexible magnetic tape. Another embodiment () is realised in a planar structure in which a ferromagnetic core () is subject to a magnetic field () at an angle to the direction (F) of force application generated by laterally offset coils (). A sensor device () is fabricated in the structure.
