Luke Skywalker’s Hand
This is Luke Skywalker’s arm at the end of The Empire Strikes Back. In 1980, the Star Wars community called them cybernetic limb replacements. While Luke’s hand is not real, it’s fully functioning fingers and lightsaber-fighting capabilities foreshadowed more advanced prosthetic limbs. Here are some of today’s coolest prosthetics. Some are still in prototype, while others are currently being used by amputees.
