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.
