R&D: Medical
A single strand of fiber has the flexibility of cotton and the electric conductivity of a polymer, called polyaniline. The newly developed material showed good potential for wearable e-textiles. Researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas.
