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."
