  • Patent number: 12135246
    Abstract: A wirelessly powered resistive sensor is presented. The sensor includes: an antenna; a parametric resonator and a resistive loop circuit. The parametric resonator is configured to receive a pumping signal from the antenna and operable to oscillate at two frequencies. The resistive loop circuit is inductively coupled to the parametric resonator, such that oscillation frequency of the parametric resonator changes (e.g., linearly) with changes in resistance of the resistance loop circuit. The resistance of the resistor in the resistive loop circuit approximately equals the impedance of the resistive loop circuit at one resonance frequency of the parametric resonator. The resistive sensor may further include a resonator enhancer circuit arranged adjacent to the parametric resonator and operates to resonate at frequency of the pumping signal.
