Special Issue Information
Dear Colleagues,
Energy scavenging is of significant importance as energy consumption is quickly increasing. Moreover, clean energy sources are highly desired due to their environmentally friendly properties. In 2012, Prof. Zhong Lin Wang invented the triboelectric nanogenerator (TENG) to harvest mechanical energy and convert it into useful electricity, providing a clean and alternative solution to the energy consumption crisis. The basic working mechanism is the combination of contact electrification and electrostatic induction. The further in-depth physics of TENG have demonstrated a Maxwell’s displacement current. Moreover, the contact electrification as well as the surface charge density are of great significance since the output power density is strongly relevant to them. Therefore, it is definitely important to explore more in-depth physical understandings regarding the fundamental studies of TENGs, from the origin of contact electrification to the working principles based on Maxwell’s displacement current. Furthermore, TENG can be utilized for not only mechanical energy harvesting, but also self-powered sensing systems and high-voltage applications. Hence, it is also necessary to develop the practical applications of TENGs in real conditions. Accordingly, this Special Issue titled “Triboelectric Nanogenerators: From Fundamental Research to Applications” seeks to showcase research papers, short communications, and review articles that focus on (1) the fundamental science and research related to TENG, from the origin of contact electrification to the working principles based on Maxwell’s displacement current; and (2) innovative practical applications of TENGs in mechanical energy harvesting, blue energy harvesting, self-powered sensing systems, high-voltage applications, and so on.
