In order to evaluate the influence of AC flashover on the insulation performance of Ethylene Propylene Rubber (EPR) at different temperature, the characteristic indicators were studied, based on the polarization and depolarization current (PDC). In the paper, the partial discharge inception and extinction voltage and the flashover voltage were firstly measured under AC voltage at the ambient temperature...
A paper-based electrostatic zipper actuator for printable robotics has been designed, fabricated and characterized. A simple fabrication process that utilizes paper with a carbon nanotube ink is used to create electrodes separated by either a mylar or parylene dielectric layer. A 5 cm × 1 cm actuator demonstrated a maximum static deflection of 1.8 cm and a bandwidth of approximately 12 Hz. Static...
Discharge current has been measured to diagnose the discharge modes of dielectric barrier discharge in a coaxial geometry through a mixture flows of argon and trace of air at one atmospheric pressure. Experimental results show that there are two discharge modes in the dielectric barrier discharge, corona discharge mode and glow discharge mode. The corona discharge only occurs in the tip of needle...
In this paper, a low-temperature (T=70degC) solution-phase approach has been developed for the fabrication of vertically-aligned ZnO nanoneedle arrays directly on bulk nickel substrate. The synthetic process involving no seeds, no catalysts, and no surfactants can be readily scaled up. The as-grown ZnO arrays are further used for the first time as anode materials for Li-ion batteries operated in the...
