QCM(Quartz Crystal Microbalance) is a piezoelectricity sensor with nanogram precision. However twice measurements of no-load and a load are necessary in the tradition, which will result in frequency errors when environments(such as temperature and humidity) changes. This paper affords a new design of double-core QCM for solving the time-delay problem in the QCM traditional measuring method. Reference...
Because quartz crystal is complex at high frequency vibration, the only vibration mode of QCM will be destroyed at some designs of electrode structures and couplings with other vibration modes will happen sometimes. This paper makes a 3D model for QCM and analyzes directly the coupled phenomenon of the structural and electric fields of QCM with finite element method. Through analyzing the convergence...
A new design for QCM sensors is introduced based on correlation theory, which has the properties of simple structure, good real-time ability, high anti-jamming ability, wide application and high precision. This paper provides the method for collecting the useful faint signal based on correlation theory and designs the QCM spectrum analyzer system structure. Finally, experiments on different liquids...
