技術說明

本發明提供一種聲波致動液滴裝置，其包含一第一聲源、一第二聲源、一細線、二固定柱以及至少一液滴輸送器。第一聲源包含一第一發射面，第二聲源包含一第二發射面，且第二發射面與第一發射面相對設置。細線同軸穿設於第一聲源與第二聲源之間。二固定柱連接於細線之二端。液滴輸送器包含一透明管、一液滴分配器及一溶液裝置，液滴分配器透過透明管連接於溶液裝置。藉此，本發明可透過第一聲源與第二聲源之間產生的駐波，將液滴輸送器輸送之液滴固定於細線上，並調整聲源之聲波強度以達到液滴之傳輸。 The present disclosure provides an acoustically actuated droplet apparatus. The acoustically actuated droplet apparatus includes a first sound source, a second sound source, a thread, two fixed columns and at least one droplet transporter. The first sound source includes a first emitting surface. The second sound source includes a second emitting surface, wherein the second emitting surface and the first emitting surface are arranged opposite to each other. The thread is coaxially passed through and placed between the first sound source and the second sound source. The two fixed columns are connected to two ends of the thread. The droplet transporter includes a tubing, a droplet dispenser and a solution container, wherein the droplet dispenser is connected with the solution container by the tubing. Accordingly, the present disclosure can fix the droplet transported by the droplet transporter to the thread using the standing wave generated between the first sound source and the second sound source, and adjust the sound intensity of the sound source to achieve the transport of droplet.
