Towards more reliable and smarter implantable medical devices using microtechnology: Presented by Hyowon “Hugh” Lee
Developing chronically reliable and multifunctional implantable medical devices is an
enormous challenge in biomedical engineering with significant economic and clinical
implications. Soon after implantation, biosensors often suffer from substantial performance
degradation and premature failures due to various abiotic and biotic failure modes.
Enabling technologies that improve the lifetime of these implantable biosensors can have
an enormous impact on many debilitating chronic neurodegenerative diseases that are
difficult to diagnose and treat. In this presentation, I will discuss our latest efforts to utilize
nano and microscale transducers to fabricate self-clearing implantable medical devices
including sensors and actuators. We utilize both passive and active anti-biofouling
approaches to improve the reliability and functionality of these implantable devices. As a
proof-of-concept, I will share our efforts to create chronically implantable self-clearing
catheters, electrochemical biosensor arrays, and high-performance neurostimulation

@Weldon School of Biomedical Engineering, Purdue University
Hyowon “Hugh” Lee received his M.S. and Ph.D. degrees in biomedical engineering from the University of California, Los Angeles, in 2008 and 2011, respectively. Before joining Purdue, he worked as a senior process engineer for St. Jude Medical’s Implantable electronic Systems Division where he worked on manufacturing challenges associated with implantable electronic devices such as pacemakers, implantable cardioverter defibrillators, deep brain stimulators, and spinal cord stimulators. At UCLA, he trained in the areas of neuroengineering and microfabrication under Jack Judy. His current research interest centers around improving the reliability and functionality of implantable sensors and actuators. He is a recipient of the NSF CAREER award and he recently co-founded Rescue Biomedical, LLC, which is a startup that focuses on developing a closed-loop solution for automatic naloxone delivery for opioid overdose.
