Chinese scientists have unveiled a revolutionary design of smart contact lenses that utilize radio frequency marks, with potential applications in both medicine and augmented reality (AR) technologies. The innovative lenses boast biocompatibility and invisibility, operating without the need for a battery or traditional silicon chips, making them incredibly user-friendly.
The inspiration for the development of these smart contact lenses came from the film “Mission: Impossible – Ghost Protocol,” where similar lenses with face recognition capabilities were featured. Experts believe that achieving a seamless integration of the virtual and real worlds through small contact lenses would represent the pinnacle of AR technology.
Using the method of encoding frequency, the new lenses are able to track the movement of pupils. Built-in radio-frequency identification (RFID) tags within the lenses alter their frequency based on the positioning of the eyes, enabling real-time detection of both direction and magnitude of eye movements.
These cutting-edge smart lenses have a wide range of potential applications, including health monitoring in medicine, enhancing immersion in virtual environments in AR technologies, and controlling robots through a visual interface in robotics. Additionally, they can accurately detect eye closure moments and offer high angular precision for controlling applications and games.
