Takashi Tokuda,Sachie Sugitani,Mari Taniyama,Akihiro Uehara,Yasuo Terasawa,Keiichiro Kagawa,Masahiro Nunoshita,Jun Ohta +7 more
TL;DR: In this article, a CMOS LSI-based flexible neural stimulation device with new fabrication technologies has been developed for application in retinal prosthesis, which is based on multichip architecture, which enables the LSIbased stimulation device to be flexible.
Proceedings ArticleDOI
Battery-Free. Sticker-Like, Device for Health Monitoring, Operated by Optical Power Transfer
Nattakam Wuthibenjaphonchai,Makito Haruta,Toshihiko Noda,Kivotaka Sasagawa,Takashi Tokuda,Mohamad Sawan,Sandro Carrara,Jun Ohta +7 more
TL;DR: This work presents the concept of a battery-free, sticker-like, device for a non-invasive health-monitoring sensor that would work as expected for a variety of glucose concentrations at an oxidation voltage of 0.8 V.
Proceedings ArticleDOI
Low-voltage operation of a CMOS image sensor based on pulse frequency modulation
TL;DR: In this article, a pixel circuit of a CMOS image sensor using PFM was designed for the next generation architecture of vision chips. And the photodiode is a parasitic pn diode between p-well and n-diffusion with the size of 2 micrometers squares.
Journal ArticleDOI
Biomedical Devices based on Semiconductor Microelectronics Technologies
TL;DR: Two typical devices for implantable biomedical devices are demonstrated; one is for retinal prosthesis and the other is a deep brain implantable device.
