Chen Hairong: Explore the future of nano robots

In 1959, Richard Ferman, the Nobel Prize winner and theoretical physicist, first proposed nanotechnology. He once imagined that the future nano -level micro -robot will be used to treat human diseases. In 1966, the science fiction movie "Fantastic Voyage" tells the story of five American doctors that have been reduced to micron standards and entered patients to perform vascular surgery for treatment. Ferman's ideas and science fiction movies have entrusted humans to use the urgent desire for the diagnosis and treatment of human diseases for human disease diagnosis and treatment.

Until the 1990s, with the development of the semiconductor industry and microfanan processing technology, micro -nano -robot talents were truly developed. At present, micro -nano robots are subverting the development of biomedicine, but there are still many technical difficulties in the implementation of medical scenes.

Chen Hairong, an associate professor at the School of Mechanical Engineering and Mechanics of Ningbo University, faced the technical difficulties of micro -nano robots. Through the new functional materials required for synthesis and the way of making new functional devices, it is exploring methods that can truly realize the application of micro -nano robots.

Teacher

In the fall of 2005, Chen Hairong became a freshman in the design and engineering major of Nanjing University of Aeronautics and Astronautics. Why choose a aircraft design and engineering major? He said that this is one of the best majors in Nanjing University of Aeronautics and Astronautics. For 4 years in college, Chen Hairong lived plain but fulfilling. His professional class scores are very good; in the spare time, he also serves as a tour guide in Zhongshan Mausoleum and enriches his life experience.

In Nanjing University of Aeronautics and Astronautics, the most important person for Chen Hairong must be his instructor at the time, Professor Qiu Jinhao. It is precisely because of the National Natural Science Foundation of Natural Sciences, which participated in the National Natural Science Foundation of Qiu Jinhao, Chen Hairong was able to step into the door of scientific research. His major changed from aircraft design to engineering mechanics. Under the influence of Professor Qiu Jinhao, he began to start with intelligent materials and nanomal. Research on positioning technology.

Professor Qiu Jinhao teaches students differently. During the graduate student, he assured that Chen Hairong would buy Chen Hairong to buy a nano -level positioning platform of more than 100,000 yuan. To this end, Chen Hairong surveyed for half a year, fully understood the mechanism, materials, sensors, etc. of the nano -level positioning platform, and finally determined the specific model of the purchase.

"The biggest impact of this matter on me is that, whether it is the theory of research or equipment, we must fully understand the field of research. Although everything starts from scratch, it is particularly harvested. It is a very large harvest. It is a very large harvest. Good research training. "

After graduating from a master's degree, Chen Hairong entered the New Energy Research Institute of China Institute of Electric Power Sciences, but after working for a year and a half, he found that what he was most interested in was constantly exploring new things. What Chen Hairong thought of Research. "I considers for more than half a year to decide to resign. At first, my parents didn't understand it. I spent a lot of effort to explain with them. Later, they all supported me."

After being determined to study for a doctorate, Chen Hairong began to carefully select the research group he was interested in and delivered his resume. With the help of Professor Qiu Jinhao, Chen Hairong got in touch with Professor Ni Qingqing of Nobunaga University in Japan. After discussing and discussing with him, he decided to go to Nobuna University in Japan to study for a doctorate degree. Under the guidance of Professor Ni Qingqing, he turned to the field of composite materials.

Chen Hairong talked about the reasons for the direction of the material. During the master's degree, he used the actuator made by the research group for related application research, but because he did not understand the material, he could not control the performance of the actuator, which made Chen Hairong feel very passive. "For example, I understand the materials, so if the current material nature cannot meet my research requirements, I can develop a new material to make the device I want to meet my experimental requirements."

In the spring of 2015, Chen Hairong went to Nobuna University in Japan to start a new prelude to the research.

Eventually

When he first went to Japan, Chen Hairong couldn't speak Japanese. Fortunately, he mainly communicated in English in the classroom. Therefore, he took time to learn Japanese after busy schoolwork. Come here.

"I was born in a mechanical major and knew it about the materials. It took about two months for the first synthetic composite material, but in the end I did nothing and made a loneliness." Chen Hairong said ridiculously.

Because I haven't learned any knowledge about materials before, for Chen Hairong, everything starts from scratch. So he searched from the Internet and downloaded various English or Chinese materials to learn videos, and began to make up the lesson.

What is polymer material, how to dissolve materials, what organic solvents, how the temperature of the material is prepared, what effect does the stirring speed affect, how to make vacuum conditions ... Chen Hairong sucks various material knowledge like a sponge.

"After fully understanding, I started a new round of material preparation. This time, it took about half a year to successfully synthesize the composite materials." The sense of achievement of harvest, Chen Hairong can still recall.

During studying in Japan, Chen Hairong participated in academic conferences and made academic reports every year, such as the Japanese Composite Materials Society, Asia -Australia Composite Materials Conference. "I am happy to participate in large academic conferences. This is very helpful for researchers' vision and research ideas. You can understand what the world is doing and what kind of research everyone is doing." Chen Hairong said, although he and many of Scholars' research directions are different, but the other party's thoughts will still inspire his research. Three and a half years of doctoral career passed by. Chen Hairong grew up for scientific researchers who were alone. He continued to stay at Xinzhou University to work as a postdoctoral work and serve as a part -time lecturer. During the PhD, Chen Hairong's research was mainly concentrated on flexible intelligent composite materials and flexible miniature devices.

He has developed a composite material Pzt/SMPU with dual intelligent attributes. The shape recovery rate of this material is stable at more than 94%, which can avoid the layering of the past piezoelectric composite materials and improve the structure adaptability; Smart fabrics can convert the mechanical energy of human activity into electrical energy, and can supply power to small portable electronic equipment; he establishes the molecular mechanism of shape memory composite materials, revealing the reasons why its micro mechanism cannot explain the phenomenon, and proves this through the experimental results proved this. Conclusion of a molecular mechanism. In addition, he also studied a flexible nano -positioning actuator to prevent biological objects from being damaged by rigid robots (such as probes) during micro/nano -operation.

Chen Hairong conducted in -depth exploration in the field of intelligent composite materials and achieved good results. He wanted to return what he learned to the country. Although the spread of the new crown pneumonia's epidemic made Chen Hairong's return to his return, he didn't hesitate to hesitate, and immediately played out. He returned to the motherland for 5 years in April 2020.

Tu Xing Zhiyuan

When he came to Ningbo University, Chen Hairong's plan for the future gradually became clear. Specifically, in order to further deepen research, he will be committed to the research of self -supply micro/nano robots and wearable equipment.

"Although it is a great challenge to provide continuous motivation for micro/nano robots, researching self -supply micro/nano robots will still be my main research direction in the future."

In Chen Hairong's plan, he will be committed to developing the corresponding micro/natal energy collectors, micro/accessors, and micro/Nano sensors, and then integrate to create a self -supply energy micro -energy micro -energy/ Narn robots, serving intelligent medical care. "Strengthening original leading medical equipment research, strengthening the research of clinical application innovation, and accelerating the development of intelligent medical equipment are also advocated by the country at present. I also want to do my best for this." Chen Hairong said.

Another direction of Chen Hairong is wearable equipment. He wants to woven smart fabrics that can detect the corresponding parameters of the human state by preparing smart fibers.

"In the future, wearable devices are expected to achieve real -time detection of human health." In Chen Hairong's ideal setting, people do not need to wait until the physical examination can find their own health problems, allowing patients to find hidden health hazards as soon as possible, healing early, improved, improved The health and happiness of people's lives.

In addition to Chen Hairong's research, he thought the most to teach students better. "What I do is basic research, so I always tell them that the speed of your results may be slower than others, but you don’t want to compare with others. Harbor. "

In addition, Chen Hairong also pays great attention to the working atmosphere of the laboratory. "I hope that the atmosphere of the laboratory can be as easy as possible. Students are right or wrong, I encourage them to express their views. Even if their thoughts at first may be wrong, I encourage them to encourage students to play their creativity. "

Standing at a new starting point, Chen Hairong believes that it is his most important task to give full play to his strength and explore the application of micro/nano robots. "Although I know that this process is definitely not so smooth, I will definitely stick to it and live up to the expectations of the country."
