  • Patent number: 9140671
    Abstract: A quantitative sensor and manufacture method thereof are disclosed. This quantitative sensor has a dual-mode film bulk acoustic resonator structure to achieve desirable performances in sensitivity, accuracy and efficiency. Furthermore, this quantitative sensor serves as a fluid sensor when a fluid detection metal layer is formed in a sample-receiving chamber; and this quantitative sensor may also serve as a bio sensor when biocompatible metal layer and a bio-sensing layer are formed in the sample-receiving chamber instead of the fluid detection metal layer.
    Type: Grant
