This 3D-printed prosthetic hand combines speed and strength with simplicity – TechCrunch

Prosthetic limbs have come a long way from the heavy, solid hands and legs of yesteryear, but it’s still difficult to pack a range of motion into them without complex or bulky machinery. But new research out of Cornell uses a cleverly designed 3D-printed mechanism to achieve speed and strength with simple construction — and it costs a lot less, too. “Developing prosthetic limbs requires
