Abstract: In one aspect, wireless strain gauges are described herein. In some embodiments, a wireless strain gauge comprises a radio frequency identification (RFID) tag and a nanocomposite backplane coupled to the RFID tag, wherein the resonant frequency of the RFID tag antenna demonstrates an exponential dependence or substantially exponential dependence on the strain sensed by the strain gauge.
