Researchers have recently unveiled a new kind of artificial limb that could be life-changing for amputees.
It's called the iLimb, and the first man in the country to receive this device is already using it to throw a football.
Mike Benning is 34 now. He lost his arm below the elbow to cancer when he was 14.
"When I want to open my hand, I will fire this muscle and it will open," Benning said.
"Simple things like that that we all take for granted around the house now have become easier for me. I've just gained another 15 minutes in my day."
His new hand is powered by sensors that detect muscle activity, like twitches to prompt movement. It can also be paired with a mobile device and special app that directs the hand into 24 different grip positions.
It's not cheap, but some groups like "The One Fund" have already raised about $30 million to help more than 250 amputees on a waiting list for these high-tech helpers.
