Worlds First Elastic Electric/Data/USB Cables

This is Roboden the World's First Elastic Electric, Data and USB CableS developed by Asahi Kasei Fibers. "We manufacture Spandex, an elastic textile, so we make fabrics that expand and contract to fit the human body. As a result, we know that human skin can stretch by a factor of 1.5. So we thought, if we can make a cable that stretches by a factor of 1.5, it could be used for wearable electronics, or for wiring the skin of humanoid robots. Those were the future applications we had in mind when we began development."
