NEW DELHI, May 18: Researchers have developed a wearable polygraph system designed to sense underlying stress hidden deep within the body. The lightweight, bandage-like device, described in a paper in the journal Science Advances, gently adheres to the chest, where it simultaneously measures heart activity, breathing patterns, sweat response, blood flow and temperature. Together, the signals capture a real-time, whole-body view of stress, the researchers, from the US’ Northwestern University and Sungkyunkwan University in the Republic of Korea, said. “Sometimes, […]
