A gravimetric sensor includes a piezoelectric resonator and an encapsulating layer formed on the surface of the resonator. The encapsulating layer defines a channel within the encapsulating layer on the surface of the resonator. The sensor is fabricated by forming a piezoelectric resonator, forming a sacrificial layer on a surface of the piezoelectric resonator, forming an encapsulating layer over the sacrificial layer on the resonator, and etching the sacrificial layer to remove the sacrificial layer and form a channel on the surface of the resonator. The sensor is used by supplying the liquid to the channel of the gravimetric sensor, operating the piezoelectric resonator, detecting a change in a resonant frequency of the resonator, and determining a presence of the analyte in the liquid from the change in resonant frequency of the resonator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices and methods for gravimetric sensing in liquid environments","description":"Devices and methods for gravimetric sensing are disclosed.
