Nature Magazine's website this morning has a report on research being performed that will make way for stretchable circuits. The researchers are using thin gold filaments shaped like 2 dimensional springs to create circuits that can bend and stretch up to 50% longer than the printing area. This research may help create fabric-based circuits that are more tolerant of movement and also allow printing of circuitry on stretchier materials like Lycra. It may also mean more reliable electronic circuits in products that we already know, such as home-based dance pads.
