Newly discovered electrochromic polymer fibers can change colors when an electric current is applied. Currently, they can only go from deep blue to orange. The researcher who discovered them is making a big mental leap and saying they could be used in color-changing clothing, but they’ve got a ways to go until that happens. This is interesting nonetheless, and for those of you who like to invest in early technologies, this might be a good bet, although it’s a long shot.
