  • Abstract
    This paper presented an optimal design on GC/SAW gas sensors by adjusting the resonant cavity of the SAW device used in the sensor system. Experimental results from the developed sensor system towards dimethyl methylphosphonate (DMMP) detection indicated that short the resonant cavity of the SAW resonator will concentrate the acoustic energy to the central area, hence, higher sensitivity was achieved.
