我们提出了一种薄膜设备，可以连接到平坦的表面，包括触摸面板，远程减少表面摩擦，通过辐射空气中的超声波。在这篇文章中，我们提出了一种薄膜空气共振结构，产生大振幅的表面振动的空气超声波激发。我们通过模拟证实，表面振幅增加到足以在设计频率下减少摩擦的水平。在使用原型的实验中还观察到，手指和膜表面之间的摩擦急剧减小，并且当用手指触摸时，表面以足够的振幅振动。
We propose a film device that can be attached to flat surfaces, including touch panels, to remotely reduce surface friction by irradiating airborne ultrasound. In this article, we present a film-air resonance structure that produces large-amplitude surface vibrations excited by airborne ultrasound. We confirmed via simulation that the surface amplitude increases to a level sufficient to reduce friction at the designed frequency. It was also observed in an experiment using a prototype that the friction between a finger and film surface is sharply reduced, and the surface vibrates with sufficient amplitude when touched with a finger.
