Bionic Hand Brings Benefits to Iraq Veteran
You know that scene in Star Wars: The Empire Strikes Back when Luke loses his hand, but the droid gives him a fake one? Well, science fact has caught up with science fiction! The bionic hand is now a reality!
Two years ago, Sgt. Juan Arredondo was serving in Iraq when a roadside bomb exploded. He lost his left hand in the attack. After months of rehabilitation, he was fitted with a prosthetic hand. But Juan wasn't happy with it. "It looks like a lobster claw, just opens and closes."
Then he saw the i-LIMB. The i-LIMB is an artificial hand that can detect electronic signals in the arm muscles. These signals tell the i-LIMB how to move the hand. The ability for a machine to interact with the body is known as bionic.
Through bionics, the hand can make four different grips. It can even point its finger to type on keyboards and dial phones. The strength of the movement can also be controlled. Juan can even pick up a Styrofoam cup without crushing it! Turning keys, opening doors, and holding a baseball are all activities that he can now easily do.
Sgt. Arredondo now works for the Wounded Warrior Project. The WWP helps soldiers like Juan recover from their injuries.
I'm Adelbert and that's what happened in Science this week!
