Luke Skywalker has inspired real-life scientists to create artificial skin capable of replicating the sensation of touch. The Star Wars saga has been a cultural juggernaut since the first movie debuted in theaters in 1977. The original trilogy focused on the story of Luke Skywalker and his quest to learn about the Force and redeem his father. This storyline has inspired countless other films, books, series, and fan works; references to it have touched every corner of popular culture.

Possibly the most iconic scene in any Star Wars work comes in the 1980 film The Empire Strikes Back. During a duel with Darth Vader, Luke loses his hand and learns that Vader did not kill his father, but that Vader is in fact his father. Luke narrowly escapes the encounter and goes on to get a new, artificial hand to replace the one that he lost in the duel. Though robotic, the new hand appears to look and function just as his human hand did. Now, forty years after the film's original release, the Star Wars tech has inspired scientists in this galaxy.

According to Reuters, researchers in Singapore have developed artificial skin aimed to help those with prosthetic limbs regain the sensation of touch, a development sparked by Luke's prosthetic hand in the Star Wars franchise. Though the skin, called the Asynchronous Coded Electronic Skin or ACES, is still in its experimental stage, the invention has generated excitement from the medical community. The team at the National University of Singapore report that the invention can process information even faster than the nervous system, and can recognize between twenty and thirty different textures. While human skin can only determine texture by moving across a surface, ACES is able to immediately determine texture with a single touch.


While this development is certainly promising, it's hardly the first time that scientists have looked to Star Wars for inspiration and inquiry. The United States' Strategic Defense Initiative of the 1980s was widely referred to as the "Star Wars Program." At the same time, the franchise has been credited with predicting the use of current technology like holograms and artificially intelligent robots. The series has also led to the study of the in-universe technology, including the web series Science and Star Wars, as well as an episode of Mythbusters exploring the feasibility of the galaxy's tech.

The goal of Star Wars and other science fiction works like it has never been to accurately predict technology, but rather to examine how human beings might respond to it. Even if Luke's artificial hand was simply included in the original trilogy as a plot device, that plot device planted a seed in a real scientist's mind that blossomed into a potentially life-altering invention. George Lucas may not have created the technology of Star Wars with the intention to change science on Earth, but this development proves once again that he has. As long as Star Wars remains the cultural force that it is, it's safe to assume science will continue to look towards the franchise for inspiration.
