Capacitor of 3D printing used ionic liquid gel

Abstract

In recent years, there has been a growing demand for highly safe soft robots having soft cabinet and working in a work environment close to humans, and the electronic components used in soft robots must also be made of soft materials. If the soft robot chassis can be manufactured by 3D printing, and at the same time, 3D printing technology can be used for the fabrication of the soft electronic components and the wiring process, it is expected to improve the efficiency of robot manufacturing and reduce the size of the robot. In this study, we aim to use ionic liquid-based gels, which have characteristics such as non-volatility, flame retardance, and great conductivity , as electrolyte materials for capacitors that possess unique property of tactility. An ionic-liquid-based solution that is cured by ultraviolet light irradiation and possesses flexibility and conductivity after curing is selected, and the ionic-liquid gel is fabricated using a light-curing 3D gel printer. The electrical properties of the fabricated ionic liquid gels will be measured and their performance as electrolyte materials for capacitors will be discussed.
