Robotic contact lens that allows users to zoom in with flashing eyes revealed by scientists



Scientists have created a robotic lens that is controlled by small eye movements, including double blinks for zooming and zooming.

Most soft robots are controlled manually or pre-programmed, but the lenses mimic the natural electrical signals in the human eye that are active even when the eye is closed.

Researchers at the University of California at San Diego have used this natural

They measure the electrical potential of the eye – called the "electro-oculogram signal" – and then make lenses to respond to this activity.

Leading researcher Shengqiang Cai from the University said New Scientist: "Even if your eye sees nothing, many people can still move their eyeball and generate this electro-ocular signal."

The lens is made of polymers that expand upon application of electric current.

It is controlled using five electrodes surrounding the eye that act as muscles. When the polymer becomes more prominent, the lens effectively increases.

Scientists hope that one day this can help to create a prosthetic eye or a camera that can be controlled only by the eyes.

"The system developed in this study has the potential to be used in visual dentures, adjustable glass and remotely controlled robotics in the future," researchers wrote in the article published in Advanced Functional Materials .
