Abstract
In many fields, such as electronic material, medicine and cosmetics production, it is an important proposition to generate small and uniform droplets of various liquids. In order to realize these droplets' generation, a bolt-clamped Langevin-type transducer and a micropore plate has been used. The purpose of this study is to fabricate a bolt-clamped Langevin-type transducer having small and simple structure in comparison with the previous one, and to generate droplets by using this device. First, by using a new fixation method, we have designed a bolt-clamped Langevin-type transducer whose structure is suitable for miniaturization. Next, we have generated and evaluated droplets in the air by using pure water. When the micro pore diameter, the applied air pressure and the resonance frequency were 50μm, 30kPa and 37kHz, the average diameter of pure water droplets and standard deviation of diameter were 96.1μm and 0.98, respectively.
