Abstract
An adjustable sensing capacitance microelectromechanical system (MEMS) apparatus includes an ASIC and a sensing component. The ASIC includes a top surface, a readout circuit and a plurality of electrical switches. The sensing component, configured to sensing physical quantity, includes a fixed electrode and a movable electrode. The fixed electrode includes a plurality of electrode units. The movable electrode is able to be moved relative to the fixed electrode. The electrical switches are respectively and electrically coupled to the electrode units so as to control a working status of each of the electrode units, thereby changing a sensing capacitance of the MEMS sensor.
