The Mudra Band seems like something out of science fiction. A replacement for the Apple Watch’s band, it measures electrical impulses passing through your wrist as you make gestures with your fingers, so you can control the watch with small finger movements without actually touching the watch. And while that sounds like the sort of CES concept demo that never manages to get to retail, you won’t have to wait long for Mudra; it’s set to ship in March.
