Here’s a video showing an amazing new finger prosthesis called the ‘X-Finger’ in action. The beautiful thing about the X-Finger is that when installed, it will allow amputees to fully recover their grip and do things that were previously difficult for them to accomplish. The device is fully mechanical and uses the hand’s muscles as an independent power source, meaning that it’ll never run out of juice while you’re wearing it.
Oh and one last thing, if your amputation made you lose the ability to “give the finger” to someone, the X-Finger will give it back to you. :)
