Abstract
A MEMS device can include a substrate having a first side and a second side, the substrate including an aperture extending from the first side through the substrate to the second side. The device can include a support structure coupled to the substrate the first side. The device can include a resilient structure coupled to the support structure. The device can include a rigid movable plate coupled to the support structure via the resilient structure and positioned over the aperture. The device can include a proof mass coupled to the movable plate, the proof mass extending into the aperture. The device can include an electrode located on an opposite side of the movable plate from the proof mass.
