The BrainRobotics prosthetic hand is a first in its field: an intuitive AI-powered hand that allows the user to make unlimited gestures and grips. Unlike other prosthetic hands that came before it, this one employs an algorithm that allows the hand and user to learn from each other and becomes more lifelike with each use. The device also uses eight multichannel electromyography sensors in the wrist, which enable the hand to process muscle signals from the user’s arm, allowing more accurate control over grips and hand motions. Although the product is still in the testing phase, one beta tester was able to play a piano duet with great success. “We hope our invention can give amputees the ability to proudly control prosthetics just like they are using their real hands,” says Max Newlon, the president of parent company BrainCo. When available, the hand will cost $10,000 to $15,000—relatively affordable, considering similar devices can cost significantly more. —Josiah Bates
