Our research interests are material sciences focusing on the development of functional materials, analysis of functional properties, and design and application of functional devices. Our research activities are classified into two the following categories.

(1) Development and basic understanding of chemical sensors. Major effort is directed to gas sensors using semiconducting or ion-conducting oxides.

*Semiconductor type gas sensor Wet preparation of SnO2 and WO3 for microstructure control of gas sensors. Control of micro porous structure for thin film semiconductor gas sensors. Analysis of diffusion-reaction for semiconductor gas sensors Elucidation of basic characteristics of semiconductor gas sensors. Microprobe (STM) analysis of surface properties of oxide semiconductors Development of high sensitive gas sensors for medical use. Investigation of SnO2-Co3O4 base for ultrasensitive CO sensor.                                           etc.

*Solid electrolyte type gas sensor Investigation of solid electrolyte CO2 sensor. Elaboration of compact type sensor operative at low temperature. New capacitive type gas sensor combining MIS structure and solid electrolyte. Evolution of gas sensors combining FET and solid electrolyte for NO2 detection. Design of compact NO2 sensing system using FET-combined type gas sensor. Exploration of new solid electrolytes for gas sensors.                                            etc.

(2) Development and application of novel functional inorganic materials (mostly mixed oxides or their composites) are under investigation for oxygen electrode catalysis, new type oxygen-separating membranes, ceramic coatings, by wet-process, and thin film using dielectric materials.

Design of gas diffusion-type oxygen reduction electrode. Exploration of reverse micelle method for preparation of efficient oxygen cathode. Development of oxygen electrode for metal-air battery. Development of oxygen permeable membrane with thin layer-on-porous support structure. Exploration of new materials for oxygen permeable membranes. Exploration of wet-coating of ceramics on metals. Characterization of ceramic films wet-coated on metals. Wet preparation of dielectric thin films for memory device. Exploration of high temperature PTC thermister.                                           etc.
