Beschreibung
Zusammenfassung:	At least some aspects of the present disclosure feature an RF hydration sensor in an assembly, comprises a substrate; an antenna disposed on the substrate; an RF circuit electrically coupled to the antenna; a thermal source electrically coupled to the RF circuit for changing a thermal condition of a target area; and a sensing element thermally coupled to the thermal source for sensing a temperature of the thermal source. The RF hydration sensor wirelessly receives a power from a remote transceiver and provides at least part of the power to the thermal source.
