Abstract
An RFID-based sensing system includes a piezoelectric arrangement mountable at least partially on a structure, an RFID transponder connected to the piezoelectric arrangement, and an antenna connected to the RFID transponder and/or being integrated into the RFID transponder. The piezoelectric arrangement and/or the RFID transponder are adapted to convert kinetic energy provided by the structure into electrical energy usable for powering the RFID transponder and to generate sensing information with respect to a state of the structure. The RFID-based sensing system also includes an RFID reader.
