ENERGY-ACCUMULATING RFID CIRCUIT, RFID-LABEL WITH ENERGY ACCUMULATION FUNCTION AND RELATED METHODS Russian patent published in 2021 - IPC G06K19/07 

FIELD: physics.

SUBSTANCE: disclosed RFID circuit receives a polling signal to an input terminal from the antenna and accumulates energy which is accumulated in a charge accumulation unit which generates accumulated voltage. Boost converter then increases accumulated voltage to increased voltage, which is supplied in form of output voltage to output terminal of sensor. Boost switching unit is also provided for activation of boost converter. Boost switching unit does not activate the boost converter until the voltage at the output under the action of the charge accumulation unit reaches the first threshold value. On the basis of the output voltage one or more input terminals of the sensor receive a measuring input which reflects the measured value of the measurement object, for example, mechanical stress in the pipe fixtures.

EFFECT: disclosed is an energy-storage RFID circuit for taking measurements wirelessly.
