Abstract :
Novel SAW sensor for gasses and odors has been invented. The structure has self-temperature-compensation characteristics. Sensor network which can monitor hydrogen-gas leakage from future fuel-cell cars and environments for health-care of old people and in hospitals has been proposed using this technology. In this sensor, sensing dynamic range can also be extended by utilizing both the 1st- and 3rd-harmonic frequency signals..
