ChBE Seminar Series: Creating a Soft and Stretchable Power System
Speaker: Dr. Nathan Lazarus, U.S. Army Research Laboratory
Title: Creating a Soft and Stretchable Power System
Stretchable electronics are the next generation of wearable technology, designed to be lighter, more comfortable and less intrusive than current devices. One of the biggest challenges in stretchable electronics is making electrical contact to the system, with physical wiring easily pulled out or damaged. In my talk, I will be discussing the use of room temperature liquid metals and magnetic fluids to create high performance stretchable power systems. 3D printing is used to define fluidic channels in soft elastomeric polymers for fill with conductors and magnetic materials that can freely flow, allowing devices to stretch by tens or hundreds of percent without damage. Using these approaches, we demonstrate new records in performance, including wireless power transfer efficiency as high as 92% to a stretchable system.
Nathan Lazarus has worked extensively in areas ranging from additive manufacturing to MEMS sensor design, with his Ph.D. at Carnegie Mellon in 2012 on integrating chemical sensors with measurement electronics using inkjet deposition. Since joining US Army Research Laboratory in May 2012, Dr. Lazarus’s research has focused on liquid-metal-based stretchable electronics, 3D printing and self-folding origami. He has authored/co-authored 40 refereed journal articles and a book chapter, and has 15 patents awarded or pending. Dr. Lazarus has also served as a part-time faculty member at George Washington University lecturing on microelectromechanical system design. He has received numerous awards including ARL’s Honorary Award for Engineering and the Rookie of the Year Excellence in Federal Career Award (Gold) from the Baltimore Federal Executive Board. In 2019, Dr. Lazarus was selected for the Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor given by the US government for researchers beginning their independent research careers.
