Quartz crystal microbalance with dissipation monitoring (QCM-D) generates surface-acoustic waves in quartz crystal plates that can effectively probe the structure of films, particulate composite electrodes of complex geometry rigidly attached to quartz crystal surface on one side and contacting a gas or liquid phase on the other side. The output QCM-D characteristics consist of the resonance frequency (MHz frequency range) and resonance bandwidth measured with extra-ordinary precision of a few tenths of Hz. Depending on the electrodes stiffness/softness, QCM-D operates either as a gravimetric or complex mechanical probe of their intrinsic structure. For at least 20 years, QCM-D has been successfully used in biochemical and environmental science and technology for its ability to probe the structure of soft solvated interfaces.

电化学石英晶体微天平的耗能监测用于电化学能量存储和转换的电极的原位实时机械和形态表征

具有耗散监测功能的石英晶体微天平（QCM-D）在石英晶体板中产生表面声波，可以有效探测薄膜的结构，复杂几何形状的颗粒状复合电极牢固地附着在石英晶体的一侧并与气体或液体接触相在另一侧。输出QCM-D特性由谐振频率（MHz频率范围）和以十分之几Hz的非凡精度测量的谐振带宽组成。根据电极的刚度/柔软度，QCM-D可以作为其固有结构的重量分析仪或复杂的机械探针。QCM-D具有探测软质溶剂化界面结构的能力，至少已在生物化学和环境科学与技术领域中成功使用了至少20年。
