Tough new hydrogel hybrid doesn't dry out

If you leave a cube of Jell-O on the kitchen counter, eventually its water will evaporate, leaving behind a shrunken, hardened mass—hardly an appetizing confection. The same is true for hydrogels. Made mostly of water, ...

Smart skin is powered by the objects it touches

(Phys.org)—Researchers have fabricated a smart skin that is self-powered by its frictional contact with the objects that it touches. When a honeybee crawls across the smart skin, the skin not only senses the insect, it ...

Stretchable electronics that quadruple in length

EPFL researchers have developed conductive tracks that can be bent and stretched up to four times their original length. They could be used in artificial skin, connected clothing and on-body sensors.

Squid inspires camouflaging smart materials

Researchers from the University of Bristol have shown it is possible to create artificial skin that can be transformed at the flick of a switch to mimic one of nature's masters of camouflage, the squid.

Engineers elucidate why skin is resistant to tearing

Skin is remarkably resistant to tearing and a team of researchers from the University of California, San Diego and the Lawrence Berkeley National Laboratory now have shown why.
