About

Dr. Sumanta Kumar Karan is a leading figure in the field of nanogenerators and piezotronics, with his work fundamentally advancing the conversion of mechanical energy into electrical power. His research focuses on the design, fabrication, and application of piezoelectric nanogenerators (PENGs) and triboelectric nanogenerators (TENGs), which harvest energy from ambient motion to power small-scale electronics. A key contribution is his co-authorship of the highly cited "Roadmap on nanogenerators and piezotronics" (2022, 60 citations), a comprehensive guide that has shaped the trajectory of the field by outlining current challenges and future directions. Dr. Karan’s work has been instrumental in expanding the scope of nanogenerators beyond the initial PENG concept, integrating TENGs to achieve higher efficiency and broader applicability. His research has garnered significant attention, with his most-cited papers accumulating hundreds of citations, reflecting his impact on sustainable energy solutions. Dr. Karan’s achievements include pioneering studies on flexible, biocompatible energy harvesters, positioning him as a key innovator in self-powered systems for wearable technology and IoT devices.
