retinal prosthesis restores sight
A retinal prosthesis has been developed collaboratively between researchers at Tel Aviv University in Israel and Linköping University in Sweden, that may be able to restore sight to people with certain types of blindness. The prosthesis consists of a thin circular photoactive film and a pigment of semi-conducting nanocrystals. It is able to convert light into electric pulses and send those pulses to the optic nerve, without the use of any external connectors. Read more about the retinal prosthesis at Linköping University.
