作者提出了一种新的技术，利用压电厚度振动器在困能模式下工作，用于检测液位的小尺度变化。本文研究了将后向波型能量捕获应用于液位传感的可行性。研究发现，反向波型能量捕获显示出与传统捕获能量模式略有不同的传感特性。当液体表面处于周围的电极区时，观察到后波型能量捕获的谐振特性随液位的逐渐变化
The authors have presented a new technique that employs a piezoelectric thickness vibrator operating in a trapped-energy mode for detecting a small-scale variation in liquid level. In this study, the feasibility of applying backward-wave-type energy trapping to liquid level sensing is investigated. It has been found that backward-wave-type energy trapping shows a sensing property slightly different from those obtained using conventional trapped-energy modes. Gradual variations in resonance characteristics with liquid level have been observed for backward-wave-type energy trapping when the liquid surface is in the surrounding electroded region
