University of Massachusetts, Amherst researchers have unveiled physiological-sensing textiles that can be woven or stitched into sleep apparel.
Their "phyjama" design exploits the fact that certain parts of sleepwear press against the wearer's body due to posture and contact with outside surfaces.
The researchers combined a fabric-based pressure sensor with a triboelectric sensor triggered by changes in physical contact to create a distributed sensor suite that could be incorporated into loose-fitting clothes.
The researchers also utilized companion data analytics to meld signals from many points that accounted for the quality of the signal from each location.
User studies indicated the phyjamas can read heartbeat peaks with high precision, breathing rate with less than one beat per minute error, and can perfectly forecast sleep posture.
