Electronic circuits can be fiddly to make: engineers have to snap components onto a board or etch designs onto a copper surface. Now a US group of researchers has demonstrated that all you really need is a pen and some paper.
The new method, which uses a rollerball pen to be filled with conductive ink, could enable engineers to create one-off circuits that are cheap, flexible and disposable. ‘Pen-based printing allows one to construct electronic devices “on-the-fly”,’ says group leader Jennifer Lewis, at the University of Illinois at Urbana-Champaign.
