Researchers have developed a rechargeable lithium-ion battery in the form of an ultra-long fiber that could be woven into fabrics. The battery could enable a wide variety of wearable electronic devices, and might even be used to make 3D-printed batteries in virtually any shape.

The researchers envision new possibilities for self-powered communications, sensing, and computational devices that could be worn like ordinary clothing, as well as devices whose batteries could also double as structural parts.

In a proof of concept, the team behind the new battery technology has produced the world’s longest flexible fiber ...

A team of researchers from the National University of Singapore (NUS) has created a novel film that is very effective in evaporating sweat from our skin to keep us cool and comfortable when we exercise, and the moisture harvested from human sweat can be used to power wearable electronic devices such as watches, fitness trackers, and more.

Sweating is a natural process for our body to reduce thermal stress. “Sweat is mostly composed of water. When water is evaporated from the skin surface, it lowers the skin temperature and we feel cooler...

An ultrathin film that is both transparent and highly conductive to electric current has been produced by a cheap and simple method devised by nanomaterials researchers from the Uni of Illinois at Chicago and Korea University. The film – actually a mat of tangled nanofiber, electroplated to form a “self-junctioned copper nano-chicken wire” – is also bendable and stretchable, offering potential applications in roll-up touchscreen displays, wearable electronics, flexible solar cells and electronic skin.

The new film establishes a “world-record combination of high transparency and low electrical resistance,” the latter at least 10X greater than the previous existing record, said Prof Sam Yoon, Korea Univ...
