Recently, with the progress of an aging society, the number of people who have suffered from retinal diseases such as retinitis pigmentosa (RP) and agerelated macular degeneration (AMD) has been remarkably increasing. However, the proper medical treatments for such diseases have not been established yet. Due to strong demands on alternative medical treatments to restore visual sensation for bli...
Variable bandgap conjugated donor–acceptor small molecule thin films show absorption spectra similar to those of human eye's photoreceptors. Photoactive devices interfaced with a bio-electrolyte reveal capacitive photocurrent response making them suitable for future full-colour retinal prosthesis.
Retinal prostheses, which restore partial vision to patients blinded by outer retinal degeneration, are currently in clinical trial. The Argus II retinal prosthesis system was recently awarded CE approval for commercial use in Europe. While retinal prosthesis users have achieved remarkable visual improvement to the point of reading letters and short sentences, the reading process is still fairl...
We review recently obtained results for CMOS (Complementary Metal Oxide Semiconductor) imaging devices used in biomedical applications. The topics include dish type image sensors, deep-brain implantation devices for small animals, and retinal prosthesis devices. Fundamental device structures and their characteristics are described, and the results of in vivo experiments are presented. key words...
