A miniaturized quartz-crystal resonator array for multiple chemical sensing in liquid

Compared with the common bio-analysis techniques, a miniaturized quartz-crystal resonator array could be the key for low cost sensing system because quartz-crystal resonator is easily miniaturized, and capable of direct chemical sensing in liquids. In this paper, we present a unique fabrication process and application of a miniaturized quartz-crystal resonator array for multiple chemical sensing in liquid.
