Wait, what happened to wireless gadget charging, period? I'm not sure, but design firm, Frog Design, is already working on a clothing concept that is capable of sustainable charging without the need for batteries or plugging into a wall outlet. Different from the wireless charging we've seen in the past, this concept utilizes the static electricity that is generated between clothing every day and ports it into gadgets.
Essentially the design involves conductive filaments to be weaved into the fabric that will slowly collect the static electricity and eventually discharge into a gadget or other electronic device. The design firm even went as far to suggest that the build up of electricity could be discharged on command and essentially create a superhero-style force field around the individual. This is far from becoming a reality, but at least the designers out there are thinking about it.
