Alternative approach for UV sensing

A method of making a UV monitoring system for measuring a radiant exposure or flux of incident UV electromagnetic radiation, comprising:

• providing a near-field coil for wirelessly coupling the system with an external electronic device;
• providing a substrate;
• and
• providing an electronic device supported by said substrate, wherein said electronic device comprises:
• a transducer including one or more light emitting diodes (LEDs), the one or more LEDs configured to convert at least a portion of said incident UV electromagnetic radiation into an electrical current, wherein the current is characteristic of said radiant exposure or flux of said incident UV electromagnetic radiation;
• wherein absorption of the incident UV electromagnetic radiation provides at least a portion of the power for said measurement of the radiant exposure or flux of said incident UV electromagnetic radiation;
• a capacitor to store charge from the one or more LEDs;
• and
• an NFC chip configured to assess charge on the capacitor and transmit UV exposure data to the external electronic device
• wherein the near-field coil encircles the transducer, the capacitor and the NFC chip on the substrate.
