Abstract
This study demonstrates a method for gas bubble removal from glass surfaces using acoustic standing wave fields. Piezoelectric transducers generate targeted frequencies, creating radiation forces that move bubbles toward antinodes. By incorporating bubble resonance frequencies, detachment efficiency is enhanced. Simulations and experiments confirmed effective wave formation and bubble migration. A burst-mode excitation minimized thermal load, providing a non-invasive solution for maintaining optical sensor performance in liquid environments.
