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 graduationExamination of surgical operation methods in scoliosis in collaboration with Shinshu University’s Medical School. Although there are many physical training methods for weight reduction, some of them don’t reveal their eects from the viewpoint of mechanical engineers. Our simulation method demonstrates mechanical conditions in our body and the results may lead to more ecient training methods for our beautiful life!BioengineeringMichihiko KosekiAssociate ProfessorProposing reliable medical techniques through computationalbiomechanical simulationsDepartment of Machinery and RoboticsSurgical operations are sometimes required to fix severe bone fractures or muscle injuries. Here, if we can estimate mechanical conditions of our body parts and/or surgical instruments prior to the operation, the information will be greatly helpful to avoid surgical errors or further surgeries. Our laboratory examines patient-specific biomechanical simulation methods. That is, we fabricate a computational model with the exact shape of the patient based on clinical X-ray CT images, and perform analyses to estimate mechanical states of bones or artificial instruments in our body. Collaboration with medical doctors leads us to propose novel medical techniques.Associate Professor Koseki took his current position in 2009 after working as an engineer at Fujitsu Limited and an assistant professor at Tokyo Institute of Technology. His research interests include computational biomechanics, medical imaging techniques and bio-inspired robotics.Our research solutions will powerfully support medical doctors on both diagnoses and treatments for illnesses or injuries in orthopedic elds. Patients can also obtain great benets including personalized and information-rich informed consent for their own treatments. We aim to realize a world which is sensitive to the needs and desires of doctors, patients, and everyone.Outlook for researchWe regard living organs of "humans" from the perspectives of "mechanical engineering" and "information engineering.“ A diverse range of knowledge makes our students enjoy a variety of career paths after graduation.Outlook for students after graduation“Scoliosis”（Spinal axis has 3D deviation）In order to realize reliable surgical operation…BEFOREAFTERExperimental -Computational research approaches!x,y,z fixedz fixedxyz
