Can a self-sustained energy storage system be used for triboelectric nanogenerators?

A self-sustained energy storage system with an electrostatic automatic switch and a buck dc-dc converter for triboelectric nanogenerators. J. Phys. Conf. Ser. 1407, 012016 (2019). 40. Yang, J. et al. Managing and optimizing the output performances of a triboelectric nanogenerator by a self-powered electrostatic vibrator switch.

What is a high-voltage MEMS plasma switch?

A high-voltage MEMS plasma switch is developed to control a buck converter trans-ferring the energy between the buffer and the nal reservoir. The fi switch control law is provided with an automatic narrow hys-teresis loop, in order to hold the voltage across the buffer capa-citor always oscillating between two high voltage levels.

Why do we need a self-actuation switch with high-voltage and narrow HYS-teresis loop?

To overcome these issues, a self-actuation switch with high actuation-voltage and narrow hys-teresis loop is needed. Implementing such a switch with electronic circuits is more dif cult and consuming because the switch control fi needs to involve two high-voltages thresholds instead of one.

How does a Teng switch work?

The high-voltage AC pulses (Fig. 1b) generated by the TENG are recti ed by the Bennet at a much higher DC value than the peak-to-fi peak TENG output voltage. The MEMS switch is initially OFF so that the buffer capacitor (Cbuf 4.7 nF) is charged to a high voltage (>300 V) through the Bennet (Fig. 1c).

Can a teng work at high-voltages without power-consuming electronics?

In this paper, we report a self-sustained conditioning system that allows the TENG to work at high-voltages for high-energy conversion without power-consuming electronics, using an unstable charge pump (Bennet doubler) combined with a high-voltage microelectromechanical system (MEMS) plasma switch in a 2-stage circuit.

How MEMS switches can be used to control synchronized switch harvesting?

For instances, the speci cally designed MEMS switches can be applied to control the synchronized switch harvesting on inductor circuits9 which fi are used to improve the harvesting ef ciency of electret and fi piezoelectric energy harvesters.
