Imagine having the ability to zoom in on objects with the literal blink of an eye. Sounds like something out of a sci-fi flick, right? Now that hypothetical is a reality, as researchers from the University of California San Diego have designed contact lenses that use the electrooculographic signal naturally produced by our eyes to perform vision-enhancing tasks like zooming in and out.
The contacts—which are actually soft robots—feature five electrodes per lens. The electrodes are spread across the contacts to act as muscles, and are made up of layers of electroactive polymer designed to expand when they receive an electrical signal from the eye.
A glimpse into the future.
