About
Dr. Hyeji Lee is a leading innovator in the field of energy harvesting and flexible electronics, with a primary focus on piezoelectric nanogenerators. Her most cited work, "Piezoelectric Nanogenerators Fabricated Using Spin Coating of Poly(vinylidene fluoride) and ZnO Composite" (2023, 30 citations), demonstrates a pivotal breakthrough in enhancing energy conversion efficiency. By ingeniously combining poly(vinylidene fluoride) (PVDF) with a ZnO composite via spin coating, Dr. Lee achieved a dramatic increase in open-circuit voltage—from 1.2 V in pure PVDF samples to an impressive 4.2 V. This threefold enhancement represents a significant leap forward in the performance of flexible, lightweight energy devices. Her research elegantly addresses the critical challenge of low output in polymer-based nanogenerators, paving the way for self-powered wearable sensors and portable electronics. Dr. Lee’s work is highly regarded for its practical fabrication method and clear demonstration of material synergy, establishing her as a key contributor to next-generation sustainable energy solutions.
