Abstract: A method of detecting whether a microelectromechanical system (MEMS) device is hermetic includes applying at least three voltage differences between a movable part and a sensor electrode of the MEMS device to measure at least three effective capacitances, calculating a capacitance-to-voltage curve and an offset voltage of the MEMS device according to the at least three effective capacitances; and determining whether the offset voltage is within a predetermined range to determine whether MEMS device is hermetic.

Abstract: The present invention relates to a proximity sensing method for proximity sensing unit in a mobile device. The proximity sensing method comprises steps of comparing a sensed value of the proximity sensing unit with a predetermined offset value or a first predetermined range to determine if the sensed value is smaller than the predetermined offset value or if the sensed value is within the first predetermined range; and providing an offset value for confirming if an object is near the mobile device according to the determination that if the sensed value is smaller than the predetermined offset value or within the first predetermined range.
