In this work, a MEMS low-g accelerometer with three sensitive directions is designed for health monitoring applications. The accelerometer may have different sensitivity in different axes. The proof-mass of the device is suspended by four serpentine springs, and the comb drive structure is used to form the differential capacitor to measure the displacement of the proof-mass. The structure has an area of 2mm by 2mm and a thickness of 0.1mm.
