3D Printing a Power SystemDr. Nathan Lazarus, US Army Research Laboratory
Abstract:
3D printing of electronics is the next frontier in additive manufacturing, allowing fully functional systems to be rapidly manufactured at the point of need. Power devices such as inductors have remained challenging, however, with the performance of many printed conductors significantly lower than traditional technologies like printed circuit boards (PCBs). My talk will survey ARL’s efforts on creating high performance inductors using additive manufacturing, particularly using low cost, consumer-grade 3D printers. Several approaches for creating highly conductive traces are demonstrated, including fill of 3D printed channels with room temperature liquid metals and selective copper electroplating of 3D printed inks and thermoplastic composites. A fully integrated 3D printed wireless power system based on liquid metal inductors and interconnect is then demonstrated.
Bio:
Nathan Lazarus has worked extensively in areas ranging from mixed signal electronics to MEMS fabrication, with his Ph.D. at Carnegie Mellon culminating in 2012 with the demonstration of the highest recorded fractional sensitivity to date for a capacitive chemical sensor topology integrated with CMOS electronics. Since joining US Army Research Laboratory in May 2012, Dr. Lazarus’s research has focused on stretchable power systems, 3D printing and self-folding origami. He has authored/co-authored 50 refereed journal articles and several book chapters, and has 15 patents awarded or pending. He has received numerous awards including ARL’s Early Career Award, 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.
