Abstract
A displacement transducer in which relative displacement between a magnet and a Hall junction is sensed. Magnetic flux from the magnet is linked to the Hall junction in a direction perpendicular to the flow of current through the Hall junction. Relative displacement between the magnet and the Hall junction causes a change in the magnetic flux linked to the Hall junction which in turn causes a change in transverse voltage across the Hall junction. A signal representative of this voltage change is output from the transducer. The transducer may be part of a NEMS or MEMS.
