微谐振器在流体中的应用主要受到界面层中液体的粘性阻力和附加惯性所引起的强阻尼的限制。在本文中，我们提出了部分润湿的新概念，利用液体的另一个属性，它的表面能，以适应物理的微谐振器的界面的液体通过形成一个弯月面。技术上简单的批量制造的原型进行的第一次实验验证的潜力，部分润湿作为一个重要的途径，以提高粘性流体中的微谐振器的品质因数的值高达600超过传统的微谐振器的几乎两个数量级。
The application of microresonators in fluids is predominantly constrained by the strong damping caused by the viscid drag and the additional inertia of the liquid in the interfacial layer. In this paper we propose the new concept of partial wetting that exploits another property of liquids, its surface energy, to adapt physically the interface of the microresonator to the liquid by the formation of a meniscus. First experiments performed with technically simple batch-fabricated prototypes validate the potential of partial wetting as a vital route to improve the quality factor of microresonators in viscid fluids to values up to 600 exceeding those of conventional microresonators by almost two orders of magnitude.
