Exploring the Dissipation Parameter of Quartz Crystal Resonator under 3-Overtone Mode

The quartz crystal resonator (QCR) as a core part of quartz crystal microbalance (QCM) sensor has been applied in sensing and measurement area. Hence, the dissipation parameter (∆D-factor) of QCR is a key detection index for QCM sensors, and it carries a lot of information about the detected substance and the detection process. However, there are few papers to study the dissipation parameter ∆D of QCM resonator under 3-overtone mode. Therefore, it is necessary to investigate the ∆D parameter of QCM resonator under 3-overtone mode. The experimental results show that the actual 3-overtone dissipation parameter D

is 2∼4 times that of nominal 3-overtone dissipation parameter D
