Could new device restore sight to blind people?


Date: 18.05.2021

A researcher at the University of Sydney is developing a printable device that acts like a retina and could one day restore sight to blind people.

Dr Matthew Griffith, from the Australian Centre for Microscopy & Microanalysis and the School of Aerospace, Mechanical and Mechatronic Engineering, has created an electrical device from multi-coloured carbon-based semiconductors -that uses absorbed light to fire the neurons that transmit signals from the eyes to the brain, acting as an artificial retina for those who have lost this capacity.

Dr Griffith hopes to ultimately apply this technology, a type of neural interface, to restore sensory function to those with spinal cord injuries, and to treat people with neurodegenerative diseases. A neural interface is a device that interacts with an individual's nervous system to record or stimulate activity.

Dr Griffith's device can be printed using the same, low-cost method as newspaper printing, with a high-speed roll to roll press.
