25Portable biosensor of human stress levels by using salivary biomarker. Lotus leaf and superhydrophobicity expressed by nano-periodic structure on a solid surface. Human information networks and noninvasive biosensingDepartment of Machinery and RoboticsOur laboratory has been exploring a new research field: biological measurement by analyzing salivary samples with “human”, “noninvasive”, and “biosensor” as research key words. Noninvasive biological measurement, using a variety of information obtained painlessly from the human body, is a technology to maintain human health and is used for medical diagnosis and treatment. Furthermore, our lab is also researching other technologies that can physically control wettability of material surfaces as a biomimetic technology.Professor Yamaguchi took his current position in 2015 after working as an assistant professor at Tokyo University of Agriculture and technology, an associate professor at Toyama University, and a professor at Iwate University. By applying engineering solutions to the medical eld, I have been investigating a measurement system to obtain biological information that is useful for diagnosis and to assist daily lives. Focusing on a salivary protein, which can be an eective index of sympathetic nerves activity, a quick, easy-to-use analytical method as a portable device was proposed.Outlook for researchGraduates work at manufactures such as pharmaceuticals, biotechnology, automobile and other industries. The human science and assistive technology might contribute to an aging society.Outlook for students after graduationBioengineeringMasaki YamaguchiProfessor A micro-robot walks autonomously (left) while a micro pin set moves through its environment (right), both using muscle tissue. An illustration (left) and overview (right) of how tissue could be fabricated from cells via magnetic elds BioengineeringYoshitake AkiyamaAssociate ProfessorCreating new bio-hybrid technologies for applications ranging from micro-robots to regenerative medicineDepartment of Machinery and RoboticsBy incorporating living organisms into man-made systems such as machine parts, I am working to develop new technologies that differ from existing machine systems. For example, I am currently attempting to create bio-hybrid robots with self-assembly and self-repair functions that do not require electricity or fossil fuels by incorporating muscles into systems instead of motors. At the same time, I am also developing technologies for operating cells via magnetic fields and systems for fabricating biological tissue that can be transplanted from cells.After completing a graduate program at Tokyo University of Agriculture and Technology, Associate Professor Akiyama worked at JEOL Ltd., at Tokyo University of Agriculture and Technology as a specially appointed assistant professor, and at Osaka University as a senior assistant professor before coming to his current position in 2014. His elds of specialization include biotechnology, micromachining, regenerative medicine, and the integration of the same.Modern society is dependent on fossil fuels, but experts only expect those resources to last for about 150 more years. If muscles could be used to power robots, our energy problems could be resolved. Additionally, the ability to grow three-dimensional tissue that can be transplanted from iPS cells, which are able to dierentiate into all cell types, would contribute greatly to the development of regenerative medicine.Outlook for researchI have not mentored any graduates yet in my current position, but graduates whom I mentored in my previous position have been employed by medical equipment and precision equipment manufacturers.Outlook for students after graduation
