Capacitor electrostatic breakdown

Dynamic interfacial electrostatic energy harvesting via a single wire

Recent achievements in triboelectric nanogenerator (TENG) (13–18) arising from triboelectrification and electrostatic breakdown have posed a prototype for harvesting the electrostatic energy of "artificial microlightning"—an elaborately designed discharge at microgaps between a charged dielectric material and a metal (19–21).
