摘要： A MEMS device and method comprising a MEMS structure adjacent to a SOI base; a sacrificial support operatively connecting the base to the MEMS structure; a suspension member operatively connecting the base to the MEMS structure, wherein the suspension member is longer than the sacrificial support; and an electrode operatively connected to the base. The device may further comprise a current pulse generator adapted to send a current pulse through the sacrificial support, wherein the current pulse causes the sacrificial support to detach from the MEMS structure. Moreover, the sacrificial support structures may be electrically resistive.

摘要： A magnetic sensing transducer device that senses low frequency magnetic fields by using flux concentrators that modulate the observed low frequency signal, thereby shifting this observed signal to higher frequencies and minimizing 1/f-type noise. This is accomplished by the oscillatory motion of a microelectromechanical (MEMS)-type magnetic flux concentrator operated with a magnetic sensor, preferably made on a common substrate. Such a combined device can be used in a magnetometer. Such a device is small, low-cost and has low-power-consumption requirements. The magnetic sensor can be a Hall effect or other type of magnetic sensor. At least one MEMS-type fabricated flux concentrator is used with the magnetic sensor. The concentrator oscillates at a modulation frequency much greater than the observed magnetic field being sensed by the device.

摘要： A magnetic flux switch having a substrate and an elongated rod having a first end attached to the substrate and a magnetic material attached to the second end. An electrostatic comb drive pivots the rod between a first and second pivotal position in dependence upon the input signal for the comb drive. In its first position the magnetic material is positioned closely adjacent a magnetic flux sensor on the substrate so that flux flow through the rod flows through the sensor which then generates an output signal. Conversely, with the rod in its second position, the magnetic material is spaced from the sensor so that flux does not flow through the magnetic flux sensor.
