From smart socks to workout clothes that measure exertion, wearable body sensors are becoming the latest “must-have” technology. Now scientists report they are on the cusp of using silk, one of the world’s most coveted fabrics, to develop a more sensitive and flexible generation of these multi-purpose devices that monitor a slew of body functions in real time. Yingying Zhang, Ph.D., says. “One possibility we foresee is for them to be used as an integrated wireless system that would allow doctors to more easily monitor patients remotely so that they can respond to their medical needs more rapidly than ever before.”

Body sensors, which are usually made with semiconductors, have s...
