Background Hello, I'm Takafumi Tsugawa, and today I'd like to talk about Professor Aoyagi and his work to create a injections that mimics mosquito's stings. Speaking of injections, people usually may refuse to hit it because it is so painful and a burden on patients. Some of them may refuse to hospital by reason of hating injections. On the other hands, not only when you catch a cold and have the vaccination, there are many people who have to inject under the skin every day. For example, person with diabetes have to inject under the skin to administer insulin many times a day. So research of painless injections was advanced for such people. You have some background information on painless injections. Now let's look at the focus of Aoyagi's research. Research question How should he develop a painless injection ? Methods and Data 1. He discovered the fact that a pain by injections is due to structure of needle. 2. His research team studied structure of mosquito's stings. 3. They discovered that mosquito's stings have two jagged needles and a normal needle. 4. Many companies refused the development of needles since it is different to develop. 5. But a small factory in a town produced it by the latest abrasive techniques. 6. It enabled to puncture an exact location. Conclusions and Future Research Actually it enabled to administer a drug without feeling pain. As of 2016, for the achievement, it has been shipped one million. Scientists aim to administer anyone, anywhere and expand cosmetics in future.
