Abstract: Accelerometer including a decoupling structure for fixing the accelerometer on a package and a MEMS sensor chip for measuring an acceleration. The chip is supported by the decoupling structure and includes a sensor wafer layer of a semiconductor material. The decoupling structure forms a bottom portion for fixing the decoupling structure on the package and a top portion fixed to the sensor wafer layer so that the chip is arranged above the decoupling structure. A width of the top portion in a planar direction is smaller than a width of the bottom portion and/or the sensor wafer layer in the planar direction. The decoupling structure is made of the same semiconductor material as the sensor wafer layer. The centre point of the top portion is arranged in a central region of the bottom portion. The chip includes a hermetically closed cavity which includes a seismic mass of the chip.

Abstract: An accelerometer sensor and method of controlling the sensor, the accelerometer sensor including at least one electrostatic pendular accelerometer having stationary first and second electrodes fastened to a housing and connected to an exciter circuit, and a third electrode carried by a pendulum connected to the housing, thereby being movable and being connected to a detector circuit. The exciter circuit has an output connected to a switch connected to the first and second electrodes, the switch having a first connection position and a second connection position for selectively connecting the first or second electrode to the exciter circuit. The detector circuit, the exciter circuit, the switch, and the detector circuit are connected to a control circuit arranged so the first and second electrodes are excited by pulse trains, thus keeping the pendulum in a setpoint position and determining an acceleration to which the pendulum is subjected.
