There's certainly no shortage of folks working to incorporate solar cells into clothing
, but a team of researchers from Iowa State University now look to have devised a way to make the wearable technology slightly
more discreet, with them using digital textile printing to print fabric that matches the pattern of the solar cells. The solar cells themselves are then attached using a "liquid stitch" method, although that apparently presented its own set of problems, as the application of the cells made it difficult to tie a knot. As the researchers helpfully point out in thier paper, however, a clip-on tie would solve that problem. Combine that with the special pouch for carrying your cellphone, and you've got a combo that can't be beat.
