Stretchable gold conductors bring bling to elastic electronics
This is some practical bling.
The precious metal gold can be used for purposes of good (like flexible brain implants) rather than evil (like a $9.4 million iPhone 4S). Researchers at the University of Michigan have created a stretchy conductive material out of gold nanoparticles and polyurethane that holds promise for use in flexible electronic devices.
Once embedded in polyurethane, the spherical gold nanoparticles can conduct electricity, even when the material is stretched out to twice its original length.
The nanoparticles align into a chain form when…
