OG exemplary drawing
 
1. A multi-functional substrate, comprising:
a first surface facing a first direction; and
an opposed, second surface facing a second direction opposite to the first direction,
whereby the first surface is configured as a sensor to detect an analyte of interest, the first surface including includes printed electrodes, the printed electrodes and the substrate configured to chemically react upon exposure to the analyte of interest to generate a charge buildup on the printed electrodes, and the second surface includes an integrated circuit, an antenna, and a dielectric coating layer over the integrated circuit and the antenna, the integrated circuit in electrical communication with the sensor and the antenna, the integrated circuit configured to convert data relating to the detected analyte of interest into a signal and the antenna configured to transmit the signal to an external receiver, the dielectric coating layer insulating the integrated circuit and the antenna.
