Abstract
Powerful micropumps and water treatment are essential for biomedical applications using microfluidic circuits. Therefore, we propose a rotary pump using underwater electrical discharge for biomedical applications and elucidate its design concept. Specifically, we demonstrate that by applying high-voltage pulses repeatedly, the rotary device having an asymmetrical antenna structure can rotate with the maximum angular velocity of ∼25 rad s−1, and can produce a net flow with an average velocity of ∼3.2 mm s−1 along with an instantaneous maximum flow of ∼9 mm s−1. In addition, we explain our experimental results fairly well by proposing a simple model that considers the effects of asymmetricity and electric field strength with a steric effect. Our findings should contribute to the microfluidics for biomedical applications.
使用微流控电路的生物医学应用离不开功能强大的微泵和水处理。因此,我们提出了一种用于生物医学应用的水下放电旋转泵,并阐明了其设计理念。具体而言,我们证明了通过反复施加高压脉冲,具有非对称天线结构的旋转装置可以以 25 rad s-1 的最大角速度旋转,并能产生平均速度为 3.2 mm s-1 的净流量和 9 mm s-1 的瞬时最大流量。此外,我们还提出了一个简单的模型,考虑了不对称和电场强度以及立体效应的影响,从而很好地解释了我们的实验结果。我们的研究结果将有助于微流控技术在生物医学领域的应用。
