Researchers at the Massachusetts Institute of Technology have developed a soft artificial muscle that mimics the structure and behavior of the human iris. Powered by light and made from real ...

such as the circular bands of sphincter muscle in the iris that work with the radial dilator muscles to change the size of the pupil. Complex combos of muscles like those in the iris are thought ...

The eye muscles have to be fast. Just to track an object involves at least seven different highly coordinated movements. If eye muscles were slow, we couldn't focus on anything moving around us.

Now, MIT engineers have taken a major step toward developing robots that replace rigid gears with something much softer – almost like real, living muscle tissue. In other words, they have found a way ...

Muscles in the colored part of your eye, your iris, then work to constrict or dilate your pupils, letting in more or less light as needed. 2. Medication "Certain medications can interfere with the ...

The team leveraged 3D printing and muscle cells derived from humans and mice to grow an artificial structure that pulls concentrically and radially, similar to how the human iris dilates and ...

As a demonstration, they grew an artificial, muscle-powered structure that pulls both concentrically and radially, much like how the iris in the human eye acts to dilate and constrict the pupil.
