Disclosed embodiments can pertain to process indicator enhancements. A process indicator can include a dye material that has electrical properties such as conductivity and capacitance that can be employed to determine whether observed conditions are acceptable or not to sterilize medical equipment. Furthermore, the indicators can employ amplification, a specialized antenna, or both to allow signals, such as an electronic property value, to be communicated through sterilization containers that can shield or degrade signals. A number and location of indicators can also be determined and utilized to assist in visual inspection of the indicators as well as automatic evaluation.
