Kohji Mitsubayashi received his Ph.D. from The University of Tokyo in 1994. Since 2003, he has been a professor at the Institute of Biomaterials and Bioengineering, Tokyo Medical and Dental University. His research interests include wearable biosensors, gas sensors for non-invasive bio-monitoring, and novel battery-free artificial organs (pancreas, muscles) with “Organic Engine (chemo-mechanical energy converter with biosensing technology).”
He has proposed a new device category “Cavitas sensors” in human body cavities for real-time bio-monitoring such as “Soft contact lens glucose sensors” (1995, 2008, 2009, and 2011), “Telemetric mouthguard sensors with a Bluetooth transmitter” (2016 and 2020), “Optic pharyngeal manometric sensor for deglutition analysis” (2007), etc. In 1988, he also started to develop several types of gas-phase biosensors (bio-sniffer, sniff-cam). They allow for real-time sensing and imaging of target volatiles in exhaled air, and skin gas (food and drink) with good sensitivity, gas-selectivity, and insensitivity to humidity.
