Gofrixty [22 August 2025] – A Virginia child prodigy has wowed the world with his new creation to fight the coronavirus. He created an affordable mind-controlled prosthetic arm that does not involve dangerous brain surgery. What he does demonstrates that innovation can be simple — and life-changing.
Choi began work on this project, his first, when he was still a high school student, the same time frame of the coronavirus pandemic. Most prosthetic arms on the market cost thousands of dollars, and he wanted to make something more affordable for the masses. With the help of a $75 3D printer, he made his first prototype. He iterated on the design and built a functional prosthetic arm for under $300. This is markedly different from the classical models.
Choi’s design doesn’t require surgeons implanting sensors in the brain, as is the case for many advanced prosthetics. Instead, his arm coordinates with sensors suspended over the forehead and earlobe. These sensors read brain signals, interpreting them as instructions for moving the prosthetic arm. The result is a safe, non-invasive approach that makes available to many individuals technology that they would not have had access to otherwise.
