Foreign media: A research team from the University of Science and Technology of China has developed an AI-driven infrared contact lens that allows humans to see objects in the dark even with their eyes closed. The study was published in the journal "Cell."
This contact lens converts invisible infrared light into visible light and uses artificial intelligence algorithms to process scattered light for clear imaging. It is made of soft, non-toxic polymers, is lightweight, and does not require external power.
The team used nanoparticles made of gold, sodium gadolinium fluoride, ytterbium, and erbium ions embedded in soft biocompatible contact lenses, which do not require external power, overcoming the drawbacks of traditional night vision devices being bulky and energy-consuming. Infrared light penetrates the eyelid well, making signals clearer when the eyes are closed. In the experiment, volunteers were able to recognize flickering infrared Morse code signals. The AI algorithm solves the problem of light scattering from nanoparticles, improving image clarity.
This technology has potential applications in security monitoring, medical imaging, and can also help visually impaired people with auxiliary navigation. The research team is further improving its sensitivity to surrounding infrared light sources, and it may bring more practical applications in the future.
