Triboelectric nanogenerators (TENGs) are a promising next-generation mechanical energy harvester because of their light weight, portability, and eco-friendliness. However, some requirements such as cost-effectiveness, high performance, scalability, and simple process make the real industrial applications of TENGs difficult. In this study, we first reported graphene-based TENG by layer-by-layer (LbL) technique that enables low cost, durable, scalable, and wearable TENGs. The LbL-based graphene multilayer was deposited on a flat, undulated polymer substrate or textile structure, where the graphene multilayers role as a positive triboelectric-material and electrode of devices. A graphene multilayer on a textile was demonstrated for scalable and wearable TENG operated by a single electrode mode. The simple and versatile graphene-based LbL assembly can provide some portable microelectronic applications like self-powered wireless sensors and further wearable energy harvesting devices. |
