Abstract
Aspects of the present disclosure relate to a sensor device having an integrated circuit and a monitoring loop coupled to the integrated circuit. The monitoring loop includes a first conductive trace and a second conductive trace, each having a first end electrically coupled to the integrated circuit and a second end. The monitoring loop includes a sterilant-responsive switch electrically coupling the second ends of the first conductive trace and the second conductive trace. The sterilant-responsive switch has a first impedance state and a second impedance state. The sterilant-responsive switch modifies an electrical connection between the first conductive trace and the second conductive trace based on exposure to an adequate environmental condition in an adequate sterilization process. The sensor device also includes an antenna coupled to the integrated circuit forming an antenna loop that is distinct from the monitoring loop.
