石英晶体微量天平是一种灵敏的厚度监测器，用于各种技术应用。它也是化学传感器、纳米摩擦学、润湿转变和超流体转变研究的多功能研究工具。通过用多孔金电极代替传统的金电极，有效吸附表面积和灵敏度提高了40倍，而不牺牲机械品质因数或谐振频率的稳定性。(C)2004年，美国物理学会。
The quartz crystal microbalance is a sensitive thickness monitor used in a variety of technological applications. It is also a versatile research tool for chemical sensor, nanotribology, wetting transition, and superfluid transition studies. By replacing the conventional gold electrodes with porous gold electrodes, the effective adsorbing surface area and hence sensitivity was enhanced by a factor of 40 with no sacrifice of the mechanical quality factor or the stability in the resonant frequency.
