    摘要: Provided is a micro electro mechanical system (MEMS) resonating accelerometer. The MEMS resonating accelerometer according to the present invention comprises: a first inertial mass; a second inertial mass which is spaced at a predetermined distance from the first inertial mass on a first axis; an elastic body which is provided between the first and second inertial masses so as to apply elasticity; and a tuning fork which is connected to the elastic body and measures the change of frequency according to acceleration, wherein the longitudinal direction of the tuning fork is parallel to a second axis which is perpendicular to the first axis, the elastic body has an opening portion being in a circular shape with a portion thereof removed, and one end of the tuning fork penetrates the opening portion and is connected to the inner surface of the elastic body.
