Abstract
In accordance with one embodiment, an RFID sensor assembly comprises a sensing RFID chip and a reference RFID chip. The sensing RFID chip and the reference RFID chip are configured for electrical coupling to an electronic component via a coupling arrangement. The coupling arrangement of the sensing RFID chip is configured to vary a coupling property in response to a sensed parameter.
Claims18
An RFID system comprising:
- an RFID sensor assembly with at least one pair of RFID chips in which at least one chip of the pair is a sensing RFID chip and at least one pair of the chip is a reference chip;
- and
- an RFID interrogator wherein the interrogator includes an RFID reader and a first antenna;
- wherein the at least one pair of RFID chips is coupled to a second antenna and the sensor assembly detects any combination of sensed parameters.
