Random question....I am having trouble finding a professional looking wire for my application. A wire will be suspended from a persons right are to left arm (lets say while jogging). I need to communication via usart or similar from arm to arm. I would like to find a nice, professional, maybe black matt finish or similar, wire to plug into a phone jack or similar. I do not work with this area in electronics so I am not sure where to look. A wire similar to a landline phone cable but smaller would be nice. Anyone know where to find these? I cannot find anything on digi-key or mouser. Any input is appreciated! I will not be communicating wirelessly on this application.
