A microelectromechanical system (MEMS) sensor includes a MEMS layer that includes fixed and movable electrodes. In response to an in-plane linear acceleration, the movable electrodes move with respect to the fixed electrodes, and acceleration is determined based on the resulting change in capacitance. A plurality of auxiliary electrodes are located on a substrate of the MEMS sensor and below the MEMS layer, such that a capacitance between the MEMS layer and the auxiliary loads changes in response to an out-of-plane movement of the MEMS layer or a portion thereof. The MEMS sensor compensates for the acceleration value based on the capacitance sensed by the auxiliary electrodes.
