Silver Solution Ink Makes Faster Flexible Circuits

Posted by samzenpus on from the quick-silver dept.

judgecorp writes "Silver-based compounds dissolved in ammonia could make finer and more flexible circuits, according to researchers at the University of Illinois. Existing inkjet based circuit printing systems use particles which are less predictable. The silver-based ink remains dissolved until the ammonia evaporates, and can be delivered through 100nm nozzles. In all senses, it's a better solution."

    The fact that this new ink reaches the bulk conductivity of pure silver upon annealing is nothing short of amazing. My company has been working on some printed electronics application, and most of the conductive inks (including silver based) have conductivities that are too low to conduct any useful amount of current.

    Jennifer Lewis' research group here at the University of Illinois did this work.

    They've got a link on that page to a youtube video that shows how to make and use this conducting ink, but it goes through Boing Boing and is down at the moment due to the SOPA protest.

    Seriously cool work.
