Findings on Science Reported by Researchers at University of California (A system verification platform for high-density epiretinal prostheses)

August 7, 2014

By a News Reporter-Staff News Editor at Computer Weekly News -- Fresh data on Science are presented in a new report. According to news reporting originating in Los Angeles, California, by VerticalNews journalists, research stated, "Retinal prostheses have restored light perception to people worldwide who have poor or no vision as a consequence of retinal degeneration. To advance the quality of visual stimulation for retinal implant recipients, a higher number of stimulation channels is expected in the next generation retinal prostheses, which poses a great challenge to system design and verification."

The news reporters obtained a quote from the research from the University of California, "This paper presents a system verification platform dedicated to the development of retinal prostheses. The system includes primary processing, dual-band power and data telemetry, a high-density stimulator array, and two methods for output verification. End-to-end system validation and individual functional block characterization can be achieved with this platform through visual inspection and software analysis. Custom-built software running on the computers also provides a good way for testing new features before they are realized by the ICs. Real-time visual feedbacks through the video displays make it easy to monitor and debug the system."

According to the news reporters, the research concluded: "The characterization of the wireless telemetry and the demonstration of the visual display are reported in this paper using a 256-channel retinal prosthetic IC as an example."
