Thalmic Labs is a startup in YC’s current batch.  Demo Day is still a few weeks away, but Thalmic Labs’ MYO Armband has already gotten buzz from press like Engadget, Wired, and NewScientist.  MYO (rhymes with Leo) gets its name from the Greek “myos”, meaning “muscle”.  Wearing the one-size-fits-all armband allows gesture control of your computer or smartphone.  MYO works by detecting electrical activity generated through arm movement, connects wirelessly to your device using Bluetooth, and supports programming interfaces for developers.

MYO Armband is available for pre-order now for $149 with delivery planned for later this year.  Products like this always start out as really ambitions ideas.  For any would-be founders, Y Combinator is especially interested in funding hardware startups.  Embedded below is a YouTube video of MYO in action.
