Self-powered and flexible sensitive systems are highly demanded in various situations such as daily lives, industrial production, personal health and multifunctional entertainments, but they are still facing great challenge in realization of excellent flexibility, maintenance-free property, high integration and favorable sensitivity. Herein, we demonstrate scalable construction of in-plane microscale self-powered integrated systems, composed of Si based photovoltaics as energy harvester to generate electricity, graphene-carbon nanotube micro-supercapacitors (MSCs) for energy storage, and dual-channel gas sensors for fast-response and highly selective detection towards NH3 and aniline, by a novel continuous centrifugal coating strategy. Notably, the prepared high-conducting graphene-carbon nanotube films can serve as both patterned microelectrodes of embedded MSCs and metal-free interconnects of the circuit, endowing the self-powered systems high integrity and splendid flexibility. Remarkably, the self-powered gas detection system exhibits excellent response (~20%, 100 ppm), ideal linear sensibility (from 25 ppm to 100 ppm) and outstanding selectivity to NH3 and aniline. Therefore, this work paves a novel avenue for scalable fabrication of highly integrated and self-powered multi-functional sensitive systems towards flexible electronics.
