Engineers have developed a way to detect physiological signals emanating from the skin with sticky sensors that beam wireless readings to a receiver clipped onto clothing. To demonstrate the wearable technology, the researchers stuck sensors to the wrist and abdomen of a test subject to monitor the person's pulse and respiration by detecting how their skin stretched and contracted with each heartbeat or breath. Likewise, stickers on the person's elbows and knees tracked arm and leg motions by gauging the minute tightening or relaxation of the skin each time the corresponding muscle flexed.
