Third Thumb Prosthesis
When most people think of prosthetics, they think of replacements for lost body parts. But the origin of the word meant "to add, put onto," and it's in this spirit designer Dani Clode created the Third Thumb. It attaches to your hand opposite your real thumb and uses two motors pulling against a flexible 3D-printed material to mimic the movements of your most prominent digit. The motors are controlled via pressure sensors hidden in your shoes, which communicate via Bluetooth with the wrist-bound controller.
