Additive Manufacturing for Flex Hybrid Electronics
Air Force Research Labs (AFRL) has investigated materials and methods to fabricate electronics into conformal, embedded, reconfigurable, flexible, or stretchable form factors while maintaining critical performance metrics. These flexible electronics are typically manufactured by placing thinned CMOS-based components onto a substrate, and printing the conductive interconnects to form the circuit in a ‘flex hybrid electronic’ paradigm.
However, beyond integrated circuits and interconnects, most electronics also need on-board power and communication. This talk looks at efforts to create printed batteries, printed antenna, reconfigurable antenna, and printed passives/ interconnects with the vision of a fully integrated ‘flex hybrid” electronic device. Moreover, AFRL is also researching the effect of mechanical forces on flex hybrid electronics and developing 3D-printed strategies to protect electronics from shock, compression, and vibrations.
Dr. Abigail Juhl is a Materials Research Engineer in the Materials and Manufacturing Directorate at Air Force Research Laboratory (AFRL). Dr. Juhl is leading an effort to dynamically control the propagation of acoustic waves through architected materials for application in hearing protection. She is an expert in patterning nano- and micro-scale materials over macroscale volumes. Abby received her Bachelors of Science in Materials Science and Engineering from North Carolina State University, and her Doctorate in Materials Science and Engineering from the University of Illinois Urbana-Champaign. She completed a National Research Council Postdoctoral Fellowship in the Optical Materials Branch at AFRL before starting in her current position.
