Performance improvement and functionalization of an electrode array for retinal prosthesis by iridium oxide coating and introduction of smart-wiring technology using CMOS microchips
Toshihiko Noda,Kiyotaka Sasagawa,Takashi Tokuda,Yasuo Terasawa,Hiroyuki Tashiro,Hiroyuki Kanda,Takashi Fujikado,Jun Ohta +7 more
TL;DR: In this paper, the improvement of an electrode array for retinal prosthesis is described, and two elements of fundamental technology required in next-generation prosthesis, the miniaturization of and wiring of a stimulus electrode, are investigated.
Proceedings ArticleDOI
A high-precision CMOS biophotometry sensor with noise cancellation and two-step A/D conversion
Mehdi Noormohammadi Khiarak,Kiyotaka Sasagawa,Takashi Tokuda,Jun Ohta,Sylvain Martel,Y. De Koninck,Benoit Gosselin +6 more
TL;DR: A new high-dynamic range CMOS photodetector embedding a photosensor and a high-precision two-step analog-to-digital converter (ADC) with a noise cancellation scheme enabling wide dynamic range and high energy-efficiency photocurrent quantization.
Journal ArticleDOI
Micro-sized photo-detecting stimulator array for retinal prosthesis by distributed sensor network approach
TL;DR: The novel point of the proposed device is that the flexible stimulator consists of micro-sized CMOS devices linked in a network.
Journal ArticleDOI
