Bionic Eye Technology

Visual prosthesis

A visual prosthesis or bionic eye is a form of neural prosthesis intended to partially restore lost vision or amplify existing vision. It usually takes the form of an externally-worn camera that is attached to a stimulator on the retina, optic nerve, or in the visual cortex, in order to produce perceptions in the visual cortex.

Trials for 'bionic' eye implants

BIONIC EYE TECHNOLOGY 1: Camera on glasses views image 2: Signals are sent to hand-held device 3: Processed information is sent back to glasses and wirelessly transmitted to receiver under surface of eye 4: Receiver sends information to electrodes in retinal implant 5: Electrodes stimulate retina to send information to brain

Retina Implant Technology

Retina impant technology involves the use of microelectronics and microchip electrodes surcigally implanted into the back of the eye (retina) to restore the function of the damaged light-activated cells found there (photoreceptors).

Australian bionic eye can be reality by 2020

The bionic eye was identified as a key health goal for Australia at the 2020 Summit, held in Canberra on April 19-20, and Professor Nigel Lovell, from the UNSW Australian Vision Prosthesis Group (AVPG), said a functional device can be a reality within 12 years with a concerted national effort.

Augmented Reality in a Contact Lens

Augmented reality: a technology whose time has come

Picture this: you’re sightseeing in London and stop at the Houses of Parliament. You want to know more about its history, where you can get a cup of tea and you need to find out how the Tube is running before you continue your tour.

“Augmented reality goggles would be one obvious solution,” says Pearson. “But already the technology is moving beyond that. Within the next few years, it’s possible that scientists will have created a contact lens that also doubles as a nano display, literally allowing us to view an augmented reality through our own eyes.”

Researchers at the University of Washington have already created a prototype contact lens and the US military’s Defense Advanced Research Projects Agency is working on contact-lens displays that could provide battlefield combat data.

Augmented Reality in a Contact Lens

A new generation of contact lenses built with very small circuits and LEDs promises bionic eyesight

clipped from spectrum.ieee.org

In this lens concept, an antenna at the periphery collects incoming RF energy from a separate portable transmitter. Power-conversion circuitry provides DC power to other parts of the system and sends instructions to the display control circuit. The display, at the center, might consist of LEDs, which would turn on and off, or LCD-like elements, whose transparency would be modulated by the control circuit. An energy-storage module, perhaps a large capacitor, is connected to a solar cell, which could provide a boost to the lens. A biosensor samples the surface of the cornea, performs an analysis, and provides data to the telecommunication module to transmit to an external computer.

The bionic eye: Light-curving camera that may help the blind to see

For years, scientists have set their sights on creating bionic eye transplants to help the blind see.

Yesterday they came a step closer after announcing they had made a camera that can reproduce human vision.

American researchers predict it will revolutionise digital photography and video - and one day even give the gift of sight.

New Light Sensor Mimicks Eye for Superior Camera Performance

One of the disadvantages of modern photo cameras is the flat image sensor that converts light into electric signals. Because of its shape, optics must make up for various aberrations that come to light (excuse the pun). Now scientists at Northwestern University and University of Illinois at Urbana-Champaign have developed technology that allows for building curved sensors and accompanying electronics. The technology one day might come in handy for developing artificial retinas or next generation endoscopic devices.
