1. A structural health monitoring device comprising:

  • a measuring circuit including a processing circuit communicatively coupled to a pair of electrodes attachable to a target area of a workpiece, the measuring circuit in communication with a radio circuit having an antenna configured to facilitate offboard communication; and

    an energy harvester circuit configured to provide electrical power to the measuring circuit;

    wherein the measuring circuit is configured to measure an impedance of the target area of the workpiece;

    wherein the processing circuit is configured to determine a change in the impedance of the target area indicative of a change in structural health of the workpiece; and

    wherein the radio circuit is configured to transmit information received from the measuring circuit regarding a measured impedance of the target area to an offboard reader.
