Abstract:
1. A MEMS contact acceleration switch, comprising: a first layer made of a non-conductive material; a second layer next to the first layer, the second layer being a spacer layer made of a conductive material; a third layer next to the second layer, the third layer being made of a conductive material, the third layer including a fourth layer next to the third layer, the fourth layer being another spacer layer made of a conductive material; a fifth layer next to the fourth layer, the fifth layer being a z-axis electrode made of a conductive material, the fifth layer being separated from the annular mass by a second gap; a second z-axis electrode disposed on the first layer, facing the annular mass, and separated from the annular mass by a third gap; and a plurality of conductive vias that extend completely through the first layer, the plurality of vias including a first via in electrical communication with the anchor post, a second via in electrical communication with the z-axis electrode, a third via in electrical communication with the second z-axis electrode, and a fourth via in electrical communication with the at least one x-y plane detection electrode.
