Stanford University engineers have developed a method for detecting physiological signals emitted from the skin-stick sensors attached to the body, which transmit wireless readings to a clothing-based receiver.
To experiment the technique, scientists of Stanford University tested the device by pinning the sensors on a person’s wrist and abdomen to monitor his pulse and breath by detecting how his skin stretched and contracted with each heartbeat or breathing.
Zhenan Bao, a chemical engineering professor at Stanford University, explained that this wearable technique, called BodyNet, will first be used in medical environments such as monitoring patients with sleep disorders or heart disease, and is also trying to develop other sensors capable of monitoring sweat and secretions. Other to track body temperature and stress.
Bao said: “We believe it will be possible one day to develop a set of sensors for the whole body to collect physiological data without interfering with the normal behavior of the person”.
