In the garments, body temperature is monitored through a thin-film transistor, while respiration is gauged using electrical resistance, but both technologies employ the pentacene as a sensing layer.

That led the relay, a kind of sensing device, to incorrectly conclude there was an electrical problem and tell a nearby electrical switch to isolate the perceived problem, reducing the flow of power to the Superdome during the game's third quarter.

The devices do not include electrical wiring or battery replacements, making it a likely candidate for powering remote sensor networks and medical-sensing technologies.
