Wearable devices that measure circadian rest-activity rhythms may be able to assess frailty-related health risks more than six years before an incidence occurs, according to a new study.

A self-healing, stretchy material that can expand to 22 times its original length could improve wearable tech and soft robotics.

Increased tagging of fish, seals, birds, and other animals can help fill key data gaps in understanding the world's changing climate.

A new fabric packs a deadly heat to kill viruses but without burning skin. It could change the way we make and use PPE, researchers say.

A new wearable device uses touch to direct the wearer. It could help in navigation or be useful for people with vision or hearing problems.

Fitbits fall short when it comes to accurately measuring sleep, but they perform well in capturing circadian rhythms, researchers say.

A GPS wildlife tracker that uses an animal's own movements solves a problem faced by biologists seeking to track wild animals for years: dead batteries.

Fewer than 1 in 4 people with heart disease use wearable heath trackers. Is it time to start having insurance pay for them?

An electronic tattoo that attaches to the chest and has a battery the size of a penny could provide continuous heart monitoring.

A soft, breathable, stretchable material that is nearly undetectable on a person's skin could one day allow for long-term health monitoring.
