Transparent triboelectric nanogenerator-induced high voltage pulsed electric field for a self-powered handheld printer

摘要

AbstractWind energy, considered as one of the most promising clean and sustainable energy sources, has drawn more and more attraction. Here we first designed and fabricated a self-powered printer system consisting of a transparent wind-driven triboelectric nanogenerator (TENG) serving as a power supply unit and a handheld printer as an output unit. The wind-driven TENG can generate an output voltage, a short-circuit current and a power up to 130V, 15 μA and 2mW, respectively. An electric field is obtained by applying a rectified voltage signal which is generated from the TENG between the substrate electrode and the syringe, compelling the charged ink droplet falling down onto the printing substrate. Additionally, the handheld printer system can realize color printing as well as printing conductive circuit by scavenging mouth-blown wind energy. The self-powered printer not only realizes the transition from TENG in lab into practical applications, but also provides an innovative idea of mobile devices without an electric power supply.Graphical abstractNowadays, printer is widely used every day in people’s life as one of the most important peripheral devices of computer. In this work, a portable self-powered printer system is explored where a wind-driven triboelectric nanogenerator (TENG) is employed as a power supply unit. The handheld printer system is constructed b
