非接觸式聲波控制為一新興技術，本研究在流體環境中，透過壓電元件振動產生之力，對聚乙烯微球進行抓取，並利用步進馬達移動微球，紀錄微球偏移掉落前之參數。本研究主要透過實驗與模擬之結果做比較，推估抓取力之大小與不同位置之間的關係，此分析將有助於特定尺度目標物之控制優化。;Non-contact acoustic control is an emerging technology. In the fluid environment, the polyethylene microspheres are trapped by the force generated from the piezoelectric element, and the microspheres are translated by the stepping motor, recording the related parameter before dropping or shifting. This study mainly compares the results of the experiment with simulations, estimating the relationship of the trapping force in different position. This analysis will help to optimize the control of specific size of targets.
