  • BAW sensor with enhanced surface area active region
    Patent number: 10812045
    Abstract: A bulk acoustic wave MEMS resonator device includes at least one functionalization (e.g., specific binding or non-specific binding) material arranged over a top side electrode, with at least one patterned enhanced surface area element arranged between a lower surface of the top side electrode and the functionalization material. The at least one patterned enhanced surface area element increases non-planarity of the at least one functionalization material, thereby providing a three-dimensional structure configured to increase sensor surface area and reduce analyte diffusion distance, and may also promote fluid mixing. Methods for biological and chemical sensing, and methods for forming MEMS resonator devices and fluidic devices are further disclosed.
