摘要：
Techniques and mechanisms to provide for metering acceleration. In an embodiment, a microelectromechanical accelerometer includes a magnet, a mass, and a first support beam portion and second support beam portion for suspension of the mass. Resonance frequency characteristics of the first support beam portion and second support beam portion, based on the magnet and a current conducted by the first support beam portion and second support beam portion, are indicative of acceleration of the mass. In another embodiment, the accelerometer further includes a first wire portion and a second wire portion which are each coupled to the mass and further coupled to a respective anchor for exchanging a signal with the first wire portion and the second wire portion. The first wire portion and the second wire portion provide for biasing of the mass.
