About

Harrison Loh is a materials scientist and engineer whose research sits at the intersection of advanced manufacturing, nanomaterials, and environmental sensing. He is best known for pioneering the use of direct ink writing—a form of 3D printing—to fabricate graphene-based gas sensors for industrial applications. His most cited work, "Direct Ink Writing of Graphene-Based Solutions for Gas Sensing" (2019, 54 citations), addresses a critical need in the energy sector: low-cost, reliable monitoring of gas leaks and well integrity in shale gas operations. By developing printable graphene inks and optimizing their deposition, Loh demonstrated a scalable route to sensitive, selective, and robust sensing devices. This contribution bridges additive manufacturing with real-world environmental monitoring, offering a practical solution for both performance optimization and regulatory compliance. His work has been recognized for its translational impact, combining fundamental materials design with pressing industrial challenges. Loh’s research continues to push the boundaries of printed electronics and functional nanomaterials, making him a notable figure in the growing field of 3D-printed sensors for energy and environmental applications.
