Electrifying ink
New electricity-conducting ink can be used to make flexible electronic devices. Researchers from the University of Illinois at Urbana-Champaign and Lawrence Livermore National Laboratory created a silver-nanoparticle ink that smoothly flows through a rollerball pen tip without leaking, skipping or clogging and remains stable for months. The team then drew electrodes on ordinary office paper and, with a few other ingredients, used the paper to create a flexible sheet of light-emitting diodes and a 3-D radio-frequency antenna. Such a strategy could work for making paper-based batteries and medical diagnostic devices, the researchers report online June 20 in Advanced Materials. —Rachel Ehrenberg
