Contactless manipulation of micro-bubbles through acoustic waves holds promise for medical application due to its non-invasive and painless treatment, such as drug delivery, gene therapy. However, the potential of acoustic trapping has not been exploited in full because it faces a significant challenge in describing ultrasound propagation path in complex medium. In order to accelerate the trapping procedure and enhance the stability of the trap when moving micro-bubbles, the Model Predictive Control (MPC) is introduced to calculate the ultrasound propagation path and then adjust phase of ultrasound-transducer-array. In this seminar, we will investigate the development of acoustic trapping in recent years, further with a report about our progress. In the near future, we will also utilize COMSOL simulation to validate trapping pattern.
