Measurement of QCM Mass Sensitivity Using Electrodeposition Method

In this paper, we proposed an experimental method based on electrodeposition to calculate the QCM mass sensitivity. It should be noted that there is a large error between the mass sensitivity calculated by the Sauerbrey equation and the actual mass sensitivity. The reason is that Sauerbrey equation does not consider the Gaussian distribution of the mass sensitivity. Considering this reason, we took electrodeposition method to calculate the QCM mass sensitivity. A series of electrodeposited experiments were carried out. In addition, the AFM and XRD measurements also were carried out to verify the effect of electrodeposition. The experimental results show that the electrodeposition method is very useful to measure the QCM mass sensitivity. Finally, this method provides a way to measure the QCM mass sensitivity, which can be used no matter what kind of electrode structure QCM has.
