When you hear the term wristwatch, you generally think of a timepiece that you wear on your wrist. Well someone is looking to change that definition. There isn’t a whole lot of information on his design, but I am going to assume for now that it is only a concept. The idea is a subdermal implant or “electric tattoo” that can function as a watch.
It uses your natural kinetic energy for power (not unlike some watches out there) and somehow uses a wireless signal to sync up with an external clock to make sure it is correct. It only illuminates when you hold your wrist up to look at it. A very cool idea, if it could work.
