Chinese scientists have found a kind of inorganic semiconductor, which has good ductility and flexibility at room temperature, which may be used in flexible electronics.

Researchers have developed a rechargeable yarn battery that is waterproof and flexible. It also can be cut into pieces and still work.

Solar cells have great potential as a source of clean electrical energy, but so far they have not been cheap, light, and flexible enough for widespread use. Now a team of researchers has found an innovative and promising way to improve solar cells and make their use in many applications more likely.

The rapid development of flexible and wearable electronics is giving rise to an exciting range of applications, from smart watches and flexible displays—such as smart phones, tablets, and TV—to smart fabrics, smart glass, transdermal patches, sensors, and more. With this rise, demand has increased for high-performance flexible batteries. Up to now, however, researchers have had difficulty obtaining both good flexibility and high energy density concurrently in lithium-ion batteries.

Scientists have created a customizable, fabric-like power source that can be cut, folded or stretched without losing its function.

If wearable electronics are to become commonplace, a breakthrough is required which allows them to be washable, stretchable and breathable. Using conventional inkjet techniques which are cheap, safe and environmentally friendly, researchers recently reported the successful printing of 2D material, creating integrated electronic circuits, directly onto fabrics.

A research team has developed an entirely textile-based, bacteria-powered bio-battery that could one day be integrated into wearable electronics.

Researchers have developed a flexible material that generates electricity when stressed. In future, it might be used as a sensor, integrated into clothing or even implanted in the human body, for instance, to power a pacemaker.

A two-in-one solar bio-battery and solar panel has been created by researchers who printed living cyanobacteria and circuitry onto paper.

Scientists reported significant advances in the thermoelectric performance of organic semiconductors based on carbon nanotube thin films that could be integrated into fabrics to convert waste heat into electricity or serve as a small power source.
