Kiyotaka Sasagawa,Norimitsu Wakama,Daisuke Okabayashi,Toshihiko Noda,Takashi Tokuda,Jun Ohta +5 more
TL;DR: In this paper, an image sensor pixel with dual-layer metal grid polarizer with extinction ratio over 80 in 65-nm standard CMOS technology was demonstrated and the extinction ratio can be achieved by optimizing the spacing.
Proceedings ArticleDOI
Retinal prosthesis device based on pulse-frequency-modulation vision chip
TL;DR: A retinal prosthesis device that uses an image sensor based on a pulse frequency modulation (PFM) photosensor array that is suitable for stimulating retinal cells is described.
Journal ArticleDOI
CMOS Imaging Devices for Biomedical Applications
TL;DR: Recently obtained results for CMOS (Comple-mentary Metal Oxide Semiconductor) imaging devices used in biomedical applications are reviewed, including dish type image sensors, deep-brain im-plantation devices for small animals, and retinal prosthesis devices.
Journal ArticleDOI
Fabrication of Iridium Oxide/Platinum Composite Film on Titanium Substrate for High-Performance Neurostimulation Electrodes
TL;DR: In this article, iridium oxide/platinum (IrOx/Pt) composite films were successfully fabricated on titanium substrates by chemical bath deposition and these films are expected to be used as biocompatible stimulation electrodes.
