At least some of the example embodiments are methods including measuring motion of a body by deflecting a first cantilever portion of a sensing element, and deflecting a second cantilever portion of a sensing element, the second cantilever element of the sensing element disposed opposite the first cantilever element. A first voltage having a first polarity is created across electrical leads responsive to the deflecting of the cantilever portions opposite the direction of the first acceleration of the body. The sensing element is supported by way of a mounting plate medially disposed on the sensing element.
