Materials Design for High Performance of Metal Oxide Semiconductor Gas Sensors

Our group has been conducting research on gas sensors for approximately 60 years. In the past, we have reported several important material designs and demonstrated the effectiveness of integrating them for achieving high performance. In recent years, aiming for further improvement, we have proposed and demonstrated gas sensors that combine the usefulness of these material designs with MEMS-type sensors, achieving ultra-high sensitivity and super selectivity.
