Lecture Summary

In this talk, Professor Jun Ohta will introduce the recent development of implantable devices based on microelectronics and using optoelectronic methods. Electrical stimulation and measurement can effectively control and measure biological functions, and are widely used in medical applications such as artificial retina, deep brain stimulation, and brain-machine interface. In addition, optogenetics, a rapidly developing optical method based on genetic engineering, enables light-mediated communication with neurons, providing a powerful bioscience and engineering tool. Based on these technologies, the development of implantable optoelectronic biomedical devices that use electrons and photons to measure and control biological functions in vivo is gaining momentum. Some examples of these devices will be presented using our research as an example, and challenges and prospects for the devices will be discussed.

Professor introduction

Jun Ohta received the B.E., M.E., ad Dr. Eng. degrees in applied physics, all from the University of Tokyo, Tkyo, Japan, in 1981, 1983, and 1992, respectively. In 1983, he joined itsubishi Electric Corporation, Hyogo, Japan. From 1992 to 1993, he was a Visiting Scholar with the Optoelectronics Computing Systems Center, the University of Colorado at Boulder. In 1998, he joined the Graduate School of Materials Science, Nara Institute of Science and Technology (NAIST), Nara, Japan, as an Associate Professor. He was appointed as a Professor in 2004. In 2021, he serves as an Executive Director and Vice President of NAIST. His current research interests include smart CMOS image sensors for biomedical applications and retinal prosthetic devices. He is Fellow of IEEE, JSAP, and ITE.
