Examples of NFC applications for temperature and pressure sensing. (a) Construction of a multifunctional epidermal NFC sensor. FS, filamentary serpentine; EP, electrophysiological; RTD, resistance temperature detector [45]. (b) Temperature sensing results [45]. (c) Photographs of a NFC temperature sensor on a neck [46]. (d) The result of converting the voltage measured wirelessly to temperature through calibration of the infrared (IR) camera [46].
