| Outline of Final Research Achievements |
In the present technology, a small-sized all-solid-state sensor is installed in the exhaust manifold of a diesel vehicle to instantly measure the PM concentration in the exhaust gas. Specifically, an electrochemical device, consisting of a proton conducting electrolyte and an electrode catalyst, is operated through the following processes: (1) active oxygen species are electrochemically produced in the exhaust gas; (2) the PM is oxidized by the active oxygen with 100% efficiency; (3) a large electrical signal is generated in the process of (2). This sensor enables continuous monitoring of PM, which is not possible for sensors reported so far, because it has self-regeneration ability.

| Academic Significance and Societal Importance of the Research Achievements |
活性酸素を in-situ で生成し、積極的に活用する化学センサの開発は革新的であり、しかも検知極に自己浄化能力を付与する技術はこれまでにない発想である。それ故、その他の PM センサと異なり、被検物をリアルタイムで連続的にモニタすることが可能になった（独創的な点）。ディーゼル車は大型車を中心に普及しており、PM センサは排ガス制御システムに不可欠な部品である（経済的意義）。しかも、PM が人体に与える影響は大であるので、そのような PM を完全に除去できれば、大気・都市環境の改善にも貢献できる。
