This study employs the transmitter part of an ultrasonic proximity sensor to generate a powerful ultrasonic field for medical humidification. This field is created using an arrangement of small ultrasonic transmitter transducers configured in an acoustic levitator-style setup. As droplets pass through this ultrasonic field, they undergo disintegration, leading to an accelerated evaporation process. The research findings highlight a significant change in droplet size distribution due to ultrasonics, resulting in a notable increase in the rate of evaporation. As a result, this study presents a conceptual framework for reimagining humidification devices for lung therapeutic purposes through the utilization of simple sensor technology.
本研究采用超声波接近传感器的发射器部分来产生用于医学加湿的强大超声场。该场是通过以声悬浮器风格设置配置的小型超声发射器换能器阵列产生的。当液滴穿过这个超声场时，它们会发生分解，从而导致蒸发过程加速。研究结果突出了由于超声波导致的液滴尺寸分布的显著变化，进而使蒸发速率显著提高。因此，本研究提出了一个概念框架，通过利用简单的传感器技术来重新构想用于肺部治疗目的的加湿设备。
