Abstract:
1. A device, comprising; a substrate configured to act as a first electrode of a capacitor; a dielectric material layer, at least a portion of which is disposed on said substrate; a spacing member disposed on said dielectric material layer; and a resilient element configured to act as a second electrode of the capacitor, said resilient element disposed at an angle with respect to said substrate and tensioned over said spacing member and secured on said dielectric material layer, a portion of said resilient element being spaced from the substrate at a predetermined distance to define an effective capacitance area that varies in response to movement of said resilient element such that a capacitance proportional to said movement may be sustained between said substrate and resilient element, wherein portions of both said resilient member and said spacing member contact said dielectric material layer.
