A Micromachined Resonant Magnetic Field Sensor
2000 Solid-State, Actuators, and Microsystems Workshop Technical Digest, 2000 A micromachined magnetic field sensor has been designed, fabricated and tested. Its principle of operation is based on the change of resonant frequency of a magnetically sensitive micromechanical resonator as a function of applied external magnetic field. Magnetic sensitivity is achieved by incorporating magnetically soft (permeable) or hard (permanent
