ACOUSTIC BUBBLE PROPULSION AND ROTATION FOR MEMS DEVICES A Thesis by ONDER DINCEL (original) (raw)

The thesis investigates the potential of acoustic wave actuated devices, specifically focusing on bubble cavitation and oscillation effects to achieve propulsion in micro channels. The research highlights the beneficial applications of bubbles, contrasting with previous studies that view them as undesirable. Notably, the study demonstrates the capability of achieving up to 400 RPM circular motion and 70 mm/s instantaneous propelling speed by manipulating self-trapped micro-bubbles' oscillation through various designs. This work emphasizes the feasibility of bubble-powered actuators for future medical applications.
