When a person is reading, looking at a map or looking towards the horizon, the eyes adjust the vision involuntarily and immediately, thanks to the small muscles inside the lens that allow it to change shape and condition. This is an involuntary setting, such as the viewfinder in photography, where the amount of light that enters the eyes when it reaches the retina is controlled and converted into an electrical signal that is transmitted to the brain.
According to the Washington Post, a team of researchers at the University of California at San Diego believes that, in the near future, eyeglasses and contact lenses can be invented to read and react to eye movements, in order to be able To adapt in real time to the electrical signals sent by the ocular muscles. At the lens.
Prototype
According to Sheng Qiancai, a professor of mechanical and aerospace engineering at the University of California, who, along with his research team, conducts scientific studies to create new applications for software robots, a prototype of flexible robotic lens has recently been created to respond to electrical impulses, called electro-oculo-graphic signals. Electrical diagram. The initial applications are the diagnosis of the eyes and the recording of the movements that the eyes generate when they move.
"Our soft lenses rely on a very similar mechanism: what the muscles of the human eye do," says Tsai. "We use artificial muscles, flexible polymers, and we apply the effort necessary for the lens to expand or contract like real muscles.
Soft Robots
Tsai said the goal of his team is to humanize robots made of soft materials that can contact or control humans.
According to robotics experts, although robotics research is even more advanced, creating robots from materials that mimic organisms has many advantages.
Various uses
Researchers believe that non-explosive robots can be effective in search and rescue missions. The same capabilities can increase the utility of using flexible robots during intraoperative surgery or during the development of a flexible bulletproof vest.
Earlier this year, researchers at MIT and Harvard announced that they were developing a new type of flexible bulletproof vest for humans, in which a shield was designed to cover the joints, such as as the knees and elbows, using materials such as synthetic rubber used for the manufacture of car tires and watering hoses. Flexible and durable membrane covering the joints of the crab and the abdomen.
Early stage
The latest news seems to indicate that his team is about to complete commercial contact lenses, which use their technology, said Tsai, noting that their two-year research is still in its infancy.
