Thermomagnetic resonator-based temperature sensing
A thermomagnetic temperature sensor, a temperature measurement system and a method of measuring temperature employ a temperature-dependent resonant frequency of a thermomagnetic resonator to measure temperature. The thermomagnetic temperature sensor includes a thermomagnetic inductor and a capacitor connector to form the thermomagnetic resonator. The thermomagnetic inductor includes a ferromagnetic material having a temperature-dependent magnetic permeability to determine the temperature-dependent resonant frequency. A predetermined relationship between the temperature-dependent resonant frequency and temperature in a range between a maximum magnetic permeability value and a Curie temperature provides the measurement of temperature.
