A new smart and responsive material can stiffen up like a worked-out muscle, say the Iowa State University engineers who developed it. Stress a muscle and it gets stronger. Mechanically stress the rubbery material – say with a twist or a bend – and the material automatically stiffens by up to 300 percent, the engineers
Artificial eye automatically stretches to simultaneously focus and correct astigmatism and image shift. Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the
Flexible electronic parts could significantly improve medical implants. However, electroconductive gold atoms usually hardly bind to silicones. Researchers from the University of Basel have now been able to modify short-chain silicones in a way, that they build strong bonds to gold atoms. Thus, for the first time, ultra-thin conductive layers on silicone rubber can be
