The lab creates new electronics by learning from the "fluctuations" of living systems.
AboutAbout the lab
Electronics that study biology and learn from biology
The Tabata-Matsui-Seki Lab studies new electronics inspired by the "fluctuations" characteristic of living organisms.
Using laser MBE, a method that can control crystal structure at the atomic level, the lab creates new electronic materials and investigates the mechanisms by which their properties emerge.
Building on this materials work, the lab is developing energy-efficient devices that mimic how the brain works, as well as ultra-sensitive sensors that measure odors emitted by the body.
By combining oxide and bio technologies, the lab aims to create devices that contribute to disease diagnosis and health monitoring.
Key terms
- Laser MBE
- A method in which a laser is directed at a material in a vacuum to evaporate it, building up a thin film on a substrate at the atomic level
- Spin waves
- A phenomenon in which the orientation of electron "spin," the source of magnetism, propagates like a wave. It can carry information without electric current
- Terahertz waves
- Electromagnetic waves with frequencies between radio waves and light. Their frequency is comparable to that of the vibrations of intermolecular bonds

ResearchResearch themes
With "fluctuations" learned from living systems as a keyword, the lab studies new devices based on oxide thin films and nanostructures. Its work includes energy-efficient, brain-inspired AI devices, electronic noses that measure odors from the body, and highly sensitive sensing using terahertz waves.
*Illustrative imageEnergy-Efficient, Brain-Inspired AI Devices
The lab studies devices that mimic how the brain works, using spin waves, which can carry information without electric current, and spin "fluctuations." It also fabricates elements from oxide thin films that mimic the function of synapses.
*Illustrative imageElectronic Nose for Measuring Body Odors
To clarify the relationship between gases emitted by the body and health conditions, the lab is developing electronic noses capable of measuring extremely low gas concentrations. Machine learning is used to analyze the responses of multiple sensors and identify the type of gas.
*Illustrative imageHighly Sensitive Sensing with Terahertz Waves
The lab studies technology that combines terahertz waves with the special electronic properties of materials such as graphene to detect molecules with high sensitivity without labeling. It aims to apply this to noninvasive disease diagnosis.
