Maxwell's equations are fundamental key equations in physics, which are the foundation of modern wireless communication, light communication, and energy science. Nanogenerators (NGs) are based on utilizing Maxwell's displacement current as the driving force to effectively convert mechanical energy into electricity, regardless of whatever used materials are nano or not. To date, NGs have attracted extensive interest due to potential applications as self‐powered sensor networks, small power sources, and even large‐scale blue energy harvesting. Hybridized NGs are based on integrating different NGs into a system that can simultaneously/individually scavenge the different types of energies in our living environment, so that a stable and sustainable power supply can be obtained by using whatever energy is available in the environment. Since we reported the first hybrid NGs in 2009 (Chen Xu, Xudong Wang, and Zhong Lin Wang, Nanowire structured hybrid cell for concurrently scavenging solar and mechanical energies, JACS, 131, 2009, 5866–5872), a variety of NGs based on different structures have been demonstrated, including mechanical energy, solar energy, thermal energy, and even chemical energy. In recent years, hybridized NGs also include the integration of different NGs to scavenge the same type of energy but using different methods for largely enhancing the energy conversion efficiency. Part of this book will give a detailed summary about the design, performance, and applications of hybridized nanogenerators.
