Outline of Final Research Achievements

For the development of medical devices, especially the development of needle-free injection devices, using supersonic microjet which the research representatives had developed, we further improve jet control method and investigate jet penetration process using model material close to the human body organization. we successfully develop a pressure measurement method for underwater shock waves inducing microjets, and proposed a highly efficient jet generation device. In addition, we developed a simple jet generation method compared with the conventional method, and obtained important knowledge useful not only to medical instruments but also to industry. The results were published at international journals and international conferences, and were introduced at outreach activities for junior high school students.
