Abstract
The present invention relates to a microwave powered sensor assembly for microwave ovens. The microwave powered sensor assembly includes a microwave antenna to generate an RF antenna signal in response to microwave radiation at a predetermined excitation frequency. A direct current (dc) power supply circuit of the microwave powered sensor assembly is operatively coupled to the RF antenna signal to extract energy from the RF antenna signal and produce a power supply voltage. A sensor is connected to the power supply voltage and configured to measure a physical or chemical property of a food item under heating in a microwave oven chamber.
