Now, ‘phyjamas’ to measure heartbeat during sleep
have designed physiologicalsensing textiles, dubbed “phyjamas,” that contain unobtrusive, portable devices for monitoring heart rate and breathing during sleep. Researchers at University of Massachusetts Amherst said the textiles will prove useful in health care. Parts of the textile that are pressed against the body are locations where researchers can measure movements caused by heartbeats and breathing. These can be used to extract physiological variables, researchers wrote in the journal The Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies. “These advances can be useful for monitoring elderly patients, many of whom suffer from sleep disorders,” said professor Trisha L Andrew, a materials chemist.
