Abstract
An apparatus for sensing a change in environmental conditions is disclosed. The apparatus includes a coating or a wire between two surfaces that has a mechanical property changed as a result of a change in the environmental conditions. The change in the mechanical property of the coating or wire results in a change in a vibration characteristic of the apparatus, such as the frequency, phase, amplitude or quality factor. The change in the vibration characteristic can be used to determine the change in the environmental condition.
