N2 - In this paper novel printed RF temperature sensors embedded in a composite based on single and double SRRs are proposed. The resonators have been printed on fiber-glass fabrics and embedded in an epoxy composite by means of a VIC. Due to the temperature dependence of the composite permittivity, the resonance frequency changes with temperature and -0.825 MHz/°C and -0.979 MHz/°C sensitivities have been obtained for the single and double resonators respectively. The paper presents the fabrication process together with simulation and measured results. These results lead to a proof of concept of these sensors that would be suitable for use as part of a whole wireless passive sensor system in the future.
