Patent abstract
An apparatus, system and method are provided for measuring state properties without requiring an internal or proximate power supply. The apparatus provides a sensing device that is responsive to fluctuations in a state property that are encountered within the test zone. Due to the fluctuations experienced by the sensing device, a sensing signal is generated and transmitted to an optical device, such as an interferometer. The sensing signal's affect on the optical device produces an interference pattern that may be detected remotely and correlated to the fluctuation experienced by the sensing device.
