Zusammenfassung:	A structural health monitoring system may include a structural health monitoring device comprising a measuring circuit attachable to a target area of a workpiece. The measuring circuit may be communication with a radio circuit having an antenna configured to facilitate offboard communication. The measuring circuit may be configured to measure an impedance of the target area of the workpiece, and the processing circuit may be configured to determine a change in the impedance of the target area indicative of a change in structural health of the workpiece. An ambient energy harvester circuit may be configured to provide electrical power to the measuring circuit. A remote reader may wirelessly interrogate the structural health monitoring device to obtain information regarding the change in the impedance of the target area.
