New Fluid-Filled Lens Combines the Best Traits from Human and Insect Vision

Engineers at Ohio State University have imitated aspects of human and insect eyes to create what may turn out to be the next big advance in camera lens technology.

The project, described in a paper presented at the IEEE International Conference on Micro Electro Mechanical Systems, attempts to mimic the human eye’s ability to subtly change shape by utilizing a lens made from a flexible polymer. One side of the lens is outfitted with numerous dome-shaped pockets that can have fluid pumped in and out in precise increments that alter the shape of the lens.

By combining aspects of human and insect vision, the system gains the advantages of both: the accurate focusing of human vision and the wide-angle view insects rely on.

“We can combine the two,” said Yi Zhao, an associate professor of biomedical engineering and ophthalmology at Ohio State and co-author of the paper via press release. “What we get is a wide-angle lens with depth of field.”

Zhao said the system would need a number of refinements to be useful for consumer electronics, where space constraints and leakage danger make a fluid-based design impractical. Instead, future versions may incorporate piezoelectric materials than can change shape in response to changes in electrical current.

He sees significant advantages for the lens design in fields such as microscopes and laparoscopic surgery, but one of the biggest markets could be mobile phones, where a flexible lens could finally allow real zoom and adaptable depth-of-field.

    blah blah blah, don’t care.

    Idiot

    Was thinking about how eyes work and camera lenses the other day. Good to hear this kind of research is happening. If you think about it, glass seems a pretty old fashioned material these days. It can’t be long until the next big thing in lens tech come along

  • Yoav

    I want this as contact lens lol

    same as graphene…. if all the storys about graphene would come to reality we woudl live in utopia. no energy problems, no pollution problems etc.. now look around you.
    this tech is 10-15 years from production ready.
    and untuile then it is maybe replaced by soenmthing different.
    transparent graphene probably that bends like piezo elements…… lol
