报告人简介：Jiyuan Tian is currently a postdoctoral researcher in the division of “Smart Technologies for Tumor Therapy” at the German Cancer Research Center (DKFZ), site Dresden, Germany. He received his M.Sc. degree in Mechanical Engineering and Ph.D. degree from the University of Exeter, Exeter, UK in 2018 and 2023, respectively. He is the awardee of Ali H. Nayfeh Prize at the International Nonlinear Dynamics Conference in 2021. In 2025, he received the prestigious Marie Skłodowska-Curie Fellowship for his project “HyBOT”. His research focuses on wireless biomedical robots, ranging from pill-sized milli-robots to micro-robots, to contribute to early-stage diagnosis for cancer prevention and advance minimally-invasive medical interventions.
报告内容摘要：Wireless mini-robots play a crucial role in medical applications by enabling untethered operation in the human body, eliminating the location constraints imposed by wired systems. Their small scale allows for minimally invasive procedures in deep-seated or otherwise inaccessible regions, contributing to enhanced diagnostics and targeted therapeutic interventions. However, operating such robots inside the human body presents significant challenges, including complex anatomical structures, the nonlinear mechanical properties of biological tissues, and the opacity of biological environments. This talk will highlight our recent developments in wireless miniaturized medical robotics spanning from pill-sized capsule endoscopic robots to microscopic robotic systems. One key innovation is a self-propelled vibro-impact capsule robot, which can be precisely navigated within the gastrointestinal tract, particularly in the small intestine, to facilitate cancer detection. In addition, the crawling robot uses yield stress fluid as a simplified ball joint, which allows it to move forward in the biological environment while carrying objects twice its own weight under the control of a magnetic field. Furthermore, a team of crawling robot, known as TrainBot, generates around two times higher actuating force than a robot unit by forming a convoy to collaboratively carry long and heavy cargos, such as electric wires for stimulation applications. Then, I will discuss the strategies for magnetic localization and closed-loop control, which enables both wireless actuation and sensing. Our research aims to unlock new possibilities—enabling robotic systems to reach their targets with minimal invasiveness, and once at the destination, perform in-situ sensing, drug delivery, tissue biopsy, and therapeutic interventions.
