Physiological tissue function depends on electrical, chemical and mechanical signaling at multiple scales. In order to build a scientific foundation of human physiology, it is instrumental to measure and modulate diverse signals everywhere in the body, specifically in the brain. Likewise, minimally invasive insertion and actuation of medical devices may have profound impact on the timely diagnosis and treatment of neurological and cardiovascular diseases as well as cancer. We have recently invented a technology that provides rapid and safe passage for endovascular tethered microprobes regardless of the tortuosity of the vasculature. The method is based on the exploitation of elastohydrodynamic coupling between the slender device and the surrounding fluid. Leveraging this navigation technique, we have been developing a microrobotic toolkit with a cross-sectional area that is orders of magnitude smaller than the smallest catheter currently available. For applications that do not require on-board electronics, we introduced a complementary toolkit that consists of remotely actuated untethered micromachines. This talk will summarize our recent efforts in all these fronts, and discuss the potential of robotic manipulation in biomedical research.

Mahmut Selman Sakar is a Tenure-Track Assistant Professor in the Institutes of Mechanical Engineering and Bioengineering at EPFL and the head of the MicroBioRobotic Systems (MICROBS) Laboratory. He obtained his PhD in Electrical and Systems Engineering from the University of Pennsylvania in 2010. He contributed to the development of tissue-engineered biological robots while working as a postdoctoral associate at the Massachusetts Institute of Technology. He was a research scientist at ETH Zurich, exploring advanced manufacturing and magnetic manipulation techniques at microscale, before joining EPFL in 2016. His current work focuses on the applications of microrobotics in life and health sciences including mechanobiology, developmental biology, neuroscience, immunotherapy, and minimally invasive medicine. He is a recipient of ERC Starting (2017) and Proof of Concept Grants (2020).
