다국어 초록 (Multilingual Abstract)

The triboelectric nanogenerator (TENG) is a prospective sustainable energy generator among energy sources such a solid-solid contact and solid-liquid contact electrification. In this study, we reported a facile fabrication of a solid-liquid TENG based on a laser-induced graphene (LIG) patterning process, which could fabricate complicated electrode shapes. In general, the solid-liquid TENG is comprised of the interdigitated electrode and contact layers. Thus, to enhance the output performance of the TENG, a charge-storage layer was frequently utilized between the electrode and contact layers. The LIG patterning process enables the fabrication of not only the interdigitated LIG electrode layer but also a polyimide charge-storage layer for LIG-TENG with stable electrical performance. Furthermore, by optimizing the LIG electrode design, the LIG-TENG demonstrated remarkable energy harvesting ability, sufficient to charge capacitors for the operation of an electronic device. Considering the simple fabrication process and energy harvesting sustainability, the LIG-TENG could be applied to self-powered sensors, wearable devices, and smart-factory systems.
