Abstract
A microelectromechanical modulating magnetic device comprising: a base; a magnetic transducer that provides an output in response to a magnetic field associated with the base; at least one movable flux concentrator positioned to move relative to the magnetic transducer; at least one flux collector positioned to collect flux for transfer onto at least one movable flux concentrator; which transfers the magnetic flux to the magnetic transducer for detection and measurement purposes; support structure for enabling the at least one movable flux concentrators to move within a predetermined frequency range; a power source for causing the movable flux concentrators to move at a frequency within the predetermined frequency range; whereby magnetic flux may enter through the flux collector, pass through the at least one movable flux concentrator for transfer to the magnetic transducer, and due to the movement of the movable flux concentrator, the signal outputted from the transducer is modulated.
