An organic retinal prosthesis that uses flexible conductive polymers rather than hard silicon electronics successfully restored sight to blind rats, lasted six to 10 months, and functioned without external power sources or wireless receivers. Fabio Benfenati, director of the Italian Institute of Technology's Center for Synaptic Neuroscience and Technology, led the research. Via AABME.org.
