This paper proposes the design and implementation of a FPGA-based frequency measurement system for Quartz Crystal Microbalance (QCM) sensors. Using different design techniques a bandwidth of 40 MHz and a resolution of 0,05Hz is achieved. This work is part of a bigger project focused on the development of a standalone QCM system for the analysis and characterization of different paints. Two methods...
This paper presents the design of a FPGA-based digital counter for the measurement of the oscillation frequency of Quartz Crystal Microbalance (QCM) sensors. This work is part of a bigger project focused on the development of a standalone QCM system for the analysis and characterization of organic coatings. The method used to implement the digital counter is the direct frequency measurement. Therefore,...

To characterize the behavior of quartz crystal microbalance (QCM) oscillator sensors, it is not enough to determine their experimental sensitivity, but rather it is essential to study the frequency fluctuations in order to establish the sensor resolution. The development of an FPGA-based system on a chip (SoC) intended to measure the frequency noise and mass resolution of QCM sensors is presented...
