  • Radio frequency signaling system and curable composition
    Patent number: 12228536
    Abstract: A radio frequency signaling system includes a curable coating composition configured to be cured to form a cured coating and a sensor received in the curable coating composition. The sensor includes circuitry forming an inductor-capacitor circuit. The circuitry has a maximum outer diameter of 10 ?m-2.0 mm. The circuitry is configured to generate an electromagnetic field in response to an external radio frequency signal. A container configured to be monitored by a radio frequency signaling system is also provided. The container includes: a container body having an outer surface and an inner surface; a cured coating on the inner surface and/or the outer surface of the container body; and a sensor positioned in the cured coating configured to detect absorption of a fluid contained in the container body by the cured coating.
