Energy Everywhere: Nanogenerator for self-Powered Semiconductor Technologies
Nanogenerators are redefining the paradigm of sustainable energy harvesting by converting ambient thermal, mechanical, and environmental energy into electrical energy, enabling self-powered systems that overcome the challenges of battery replacement and external power supplies, particularly in distributed and remote applications. This talk will explore how everyday energy sources—including vibrations, touch, heartbeats, and wind—can be harvested to power wearable electronics, intelligent transportation systems, the Internet of Things (IoT), smart infrastructure, autonomous healthcare devices, and next-generation human–machine interfaces, while also enabling energy-autonomous semiconductor sensors and low-power electronic systems. Furthermore, recent advances in piezoelectric, triboelectric, thermoelectric, pyroelectric, and hybrid nanogenerators will be discussed, showcasing their evolution from simple energy harvesters into multifunctional platforms capable of intelligent sensing, real-time monitoring, and autonomous operation. The presentation will highlight breakthroughs in nanogenerator operating principles, simulation-driven design, advanced materials, fabrication and their integration with next-generation semiconductor technologies.
