A micromixer using direct ultrasonic vibration is first reported in this paper. The ultrasonic vibration was induced by a bulk lead-zirconate-titanate (PZT; 5 x 4 x 0.2 mm), which was excited by a 48 kHz square wave at 150 V (peak-to-peak). Liquids were mixed in a chamber (6 x 6 x 0.06 mm) with an oscillating diaphragm driven by the PZT. The oscillating diaphragm was in the size of 6 x 6 x 0.15 mm. Ethanol and water were used to test the mixing effectiveness. The laminar flows of ethanol (115 microL/min) and water (100 microL/min) were mixed effectively when the PZT was excited. The entire process was recorded using a video camera.
本文首次报道了一种使用直接超声振动的微混合器。超声振动由一块锆钛酸铅（PZT；5×4×0.2毫米）产生，该PZT由一个48千赫兹、150伏（峰峰值）的方波激发。液体在一个由PZT驱动的振荡隔膜的腔室（6×6×0.06毫米）中混合。振荡隔膜的尺寸为6×6×0.15毫米。使用乙醇和水来测试混合效果。当PZT被激发时，乙醇（115微升/分钟）和水（100微升/分钟）的层流被有效混合。整个过程用摄像机记录下来。
