Flexible , bendable and rollable electronics remain somewhat of a sci - fi ambition : make circuitry that continues to conduct electricity while undergo distortion is in reality quite laborious . But now there ’s a metal director that can stretch to twice its duration — and it ’s cheap to make , too .
The new material , develop at Washington State University , bonds a metal cinema made out of In to a plastic layer that ’s often used in electronic devices . In experiment , the squad oversee to stretch the sampling to twice its length before it fail . Even then , it was the plastic that in reality broke , and not the metal flick seat atop it .
It ’s an telling exploit . While standardized solvent have been achieved with gold in the past times , it ’s prohibitively expensive to use in turgid quantities . Meanwhile , chinchy Cu has only been show to be able to stretch by 30 pct in comparable experiments . By comparison , indium is relatively cheap and seemingly incredibly stretchable .
That makes the fresh fabric an attractive proposition for flexible electronics . Perhaps we ’re edging closer to those sci - fi dream after all .
