    摘要:

    为了降低微流分析成本,该文提出了基于智能手机检测压电基片上目标微液滴方法,并开发出相应的应用软件,通过分析微液滴颜色信息和几何信息定位目标微液滴位置,结合分析时间获取微液滴输运速度。为验证提出方法的正确性,以5 μL黑色墨水溶液微液滴为研究对象,进行压电基片上微液滴识别和位置分析实验。结果表明,该文所提方法和开发的应用软件可识别和定位压电基片上微液滴,在功率为27.5 dBm时,第2~10 s段内微液滴输运速度为0.416 mm/s。

    Abstract:

    In order to decrease microfluidic analysis cost, a smartphone-based method for detecting the position of a droplet on piezoelectric substrate is presented. An application soft is developed for sensing droplet position, which can be obtained by analyzing its color information and geometry information. In the meantime, transportation velocity of the droplet is calculated by help of the interesting time. A 5 μL black ink solution droplet is used to demonstrate the utility of the presented method. The results show that the droplet on the piezoelectric substrate can be identified and its position can be determined using the self-developed app. The average transportation velocity of the droplet is 0.416 mm/s from 2 s to 10 s at 27.5 dBm of signal power.
