AI-powered bionic hand promises lifelike dexterity

The hand is made using aviation-level aluminum and plastic. To set it up, amputees are instructed to "think" about moving individual fingers and making hand gestures while the prosthetic is attached. Meanwhile, the device measures and remembers what each signal looks like. It's ready to operate within 15 minutes, the company says. After training, the robotic hand will respond to each of the muscle triggers it picked up during the exercise.
