A team is working on a wool-based super conductor that will power new wearable monitoring devices. Via University of Nebraska Today:

A University of Nebraska­–Lincoln research team is another step closer to bringing to market a game-changing monitoring device that could streamline the day-to-day work of medical professionals and boost the mobility and independence of a variety of patient populations.

The technology stemmed from Grube’s graduate work focused on textile-based supercapacitors — battery-like devices capable of providing rapid energy surges. When used in tandem with batteries, supercapacitors can lengthen the operating life of a device by providing the quick bursts of energy that would quickly damage a typical battery. Researchers have been increasingly focused on designing textile-based supercapacitors for use in smart textiles. Because they are made of yarns like cotton, nylon and polyester, textile supercapacitors are lightweight, flexible, portable and washable — characteristics ideal for wearable devices.
