7. A system for wirelessly obtaining a moisture measurement, comprising:
a wireless reader comprising a transceiver configured to emit and receive radio frequency signals; and
a wound dressing, comprising:
a flexible substrate having a top surface and a bottom surface;
a plurality of electrochemical moisture sensor circuits disposed on said bottom surface of said flexible substrate that is configured to determine a moisture value;
an antenna circuit disposed on said top surface of said flexible substrate configured to at least receive said radio frequency signals from said transceiver;
a multiplexer in electronic communication with the plurality of electrochemical moisture sensor circuits;
a microcontroller in electronic communication with said antenna circuit and said multiplexer, thereby enabling the microcontroller to obtain, via the multiplexer, sensor data from the plurality of the electrochemical moisture sensor circuits; and
an adhesive having a top surface and a bottom surface, wherein said bottom surface of said adhesive is configured to be attached to skin of a user and wherein said plurality of electrochemical moisture sensor circuits are arranged between said top surface of said adhesive and said flexible substrate.
