JONES // DECEMBER 2009 22 December 2009Several teams of scientists and engineers have been trying for years to produce a practical retinal prosthesis for people afflicted by a progressive loss of photoreceptor cells. One problem all the researchers face is how to get power and data (the image) to a retinal chip thats implanted at the back of a persons eye. Some groups implants, such as those from the University of Southern Californias Doheny Eye Institute and an MIT-Harvard team get their power and data from RF signals beamed in from the outside, while other groups, including one at the University Eye Hospital in Tbingen, Germany, are working on getting the data as light entering the eye using RF energy to beam...
