Mark Stark’s Prosthetic Hand

Mark Stark’s prosthetic hand functions as well as an electronic model but costs only a fraction of the price. The hand works by being attached to a cable that runs from a shoulder harness worn by an amputee. The lever on the palm helps to open the hand and separate cables in each finger open and close fingers to bend around objects with a secure grip. The prosthetic hand is “gentle enough to hold a raw egg but strong enough that you can lift a chair.” Stark’s invention has been featured on the cover of Popular Science magazine.
