Researchers have crafted a vision implant with tiny electrodes, comparable in size to neurons, with the goal of restoring sight for the blind.
Vision implants utilize electrodes to convey signals to the brain, mimicking visual information akin to pixels forming an image. By reducing the size of these electrodes to a microscopic scale, researchers could accommodate more of them within a single implant. Consequently, this amplifies brain stimulation, offering a clearer and more intricate visual depiction for the user, according to the research team’s assertions.
Image clarity is crucial because the visuals generated through brain signals lack the clarity experienced by individuals with unimpaired vision.
The implant integrates a distinctive mix of materials engineered to resist corrosion. This includes a conducting polymer that not only conducts electrical signals but also acts as a protective coating over the metal.
The research team emphasizes that this material combination is essential for ensuring the implant’s longevity and optimal performance.
