| Research Abstract |
Oxygen sensors are getting much attention related to the concern in energy and environmental problems and the demand to safe, secure and comfortable life. An oxygen sensor exploiting a hot spot phenomenon we have found uses neither electrolysis solution, temperature control of material nor gold/platinum electrodes. Since improvement in a response is feasible, it can become a sensor having high flexibility and reliability. In this research, the following points were investigated aiming at the development of a hot spot oxygen sensor having a high-speed response: 1. Analysis of the diffusion of oxygen in the material. 2. Design of the composition and microstructure which increase the diffusion velocity of oxygen in the material. 3 Development of the fabrication method which realizes desired microstructure.
