Portable High Performance Gas Sensor System for Hazardous Gasses

Research Project Outline

It is required for the safety of environment to rapidly and sensitively detect many hazardous gasses. In this research, we improve the ball SAW sensor which accurately measure the effect of absorbed gas by using the multiple roundtrips of SAW on the surface of a sphere. Then, we develope a portable sensor system for many gasses using ball SAW sensors with gas separation by chromatograph columns prepared by micro fabrications.
