摘要： A tunneling accelerometer that can be implemented as a MEMS micro sensor provides differential sensing that minimizes large forces resulting from undesired environmental effects. Used as a seismic sensor, for example, the accelerometer exhibits maximum sensitivity for small seismic waves and suppresses very large seismic activities occurring at shallower depths. In one embodiment, detected current decreases from its maximum for stronger forces and is maximized for small vibrations. In another embodiment, separation of columns of top and bottom tunneling tip pairs, one column from the next, increases gradually so that the tunneling accelerometer suppresses sensitivity to large accelerations such as large seismic activity. A manufacturing process for the accelerometer provides reduced complexity for better yield.
