Abstract

A RF resonator for sensing a physical or environmental parameter includes a substrate having a substrate surface. A polymer-derived ceramic (PDC) element is positioned on or within the substrate surface. The RF resonator has a resonant frequency that changes as a function of the physical or environmental parameter. A system for wirelessely sensing at least one physical or environmental parameter includes at least one RF resonator and a wireless RF reader located remotely from the RF resonator first transmitting a wide-band RF interrogation signal that excites the RF resonator. The wireless RF reader detects a sensing signal retransmitted by the RF resonator and includes a processor for determining the physical or environmental parameter at the location of the RF resonator from the sensing signal.
