About

Hemin Zhang is a leading figure in the fields of nanogenerators, piezotronics, and self-powered nanosystems, with a particular focus on energy harvesting and wearable electronics. Their most cited work, the comprehensive "Roadmap on nanogenerators and piezotronics" (2022, 60 citations), provides a critical synthesis of the field, tracing the evolution from the first piezoelectric nanogenerator (PENG) using nanowires to the transformative invention of the triboelectric nanogenerator (TENG). This roadmap not only documents the explosive growth of the field over the past decade but also outlines future directions for integrating these technologies into practical applications. Zhang’s contributions have helped bridge fundamental materials science with device engineering, enabling the development of self-powered sensors and flexible electronics that harvest ambient mechanical energy. Their work is highly influential among researchers seeking to miniaturize power sources for the Internet of Things and biomedical devices. By systematically charting the progress and challenges of nanogenerators, Zhang has established themselves as a key voice in shaping the next generation of energy-autonomous systems.
