A new ink developed by researchers at the University of Illinois allows them to write their own silver linings. A new ink, composed of silver nanoparticles, has been developed by researchers at the University of Illinois, Champaign, IL, USA. The ink can be used in electronic and optoelectronic applications to create flexible, stretchable and spanning microelectrodes that carry signals from one circuit element to another. The printed microelectrodes can withstand repeated bending and stretchin...
