BIONIC EYE


  BIONIC EYE.ppt (Size: 1.08 MB / Downloads: 2)

Bio-electronic eye
Electronic device which replaces functionality of a part or whole of the eye
Used for replacing functionality (or)
Adding functionality to the eye

Causes of Blindness

Damage to Clear Structures in the eye, that allow the light to pass through
Retinitis pigmentosa
Age-related Macular Degeneration(AMD)

Orchard of Pillars

One side of pillar is a light sensing pixel and other side is a cell stimulating electrode.
Pillar density dictates image resolution or visual acuity.
Another design is pore electrodes

WORKING

The video camera perceives the light reflected by the object.
The processor sends the image to the infrared LED-LCD screen mounted on the goggles.
The transparent goggles reflect the infrared image into the eye and onto the retinal chip.
The infrared image electrically stimulates the implant’s array of photodiodes.

Conclusion

bionics is a creativity technique that tries to use biological prototypes to get ideas for engineering solutions.
Researchers throughout the world have looked for ways to improve people's lives with artificial, bionic devices.
Bionic devices are being developed to do more than replace defective parts.
Researchers are also using them to fight illnesses.
