MEMS TECHNOLOGIES FOR ARTIFICIAL RETINAS

摘要

The mostly cause of blindness in the developed countries is a degeneration of the retina. For restoring this loss of vision one possible approach is the substitution of the lost functions by means of an electronic implant. This approach is based on MEMS technologies. It has been shown that electrical stimulation of retinal ganglion cells yield visual sensations'. Therefore, an artificial retina for blind humans based on this concept seems to be feasible. Besides electrical stimulation of retinal ganglion cells also the direct electrical stimulation of the optic nerve2 and the visual cortex3 have been under investigation. This paper wants to give an overview about the activities on the retinal ganglion cell stimulation.
