An example device includes a rigid plate, an inner element, a plurality of connecting flexural elements coupled between the inner element and rigid plate, and a hardstop that extends through the inner element and couples to the rigid plate. The inner element has a plurality of reflective surface areas that are configured to reflect light to a sensor. The plurality of connecting flexural elements allow the inner element to move relative to rigid plate. The hardstop contacts the inner element when a load applied on the device exceeds a threshold load.
