Paper’s inherent characteristics can be exploited to overcome the limitations of conventional substrates, such as weak adhesion and large mass densities. Researchers in South Korea proposed a method for fabricating vertically integrated multi-electrodes within only a single sheet of paper. Despite the randomly distributed fibrous networks in paper, the multi-layered electrodes were uniformly formed and completely separated by applying a removable hydrophobic wax barrier confinement inside a single sheet of paper. Conventional two-dimensional planes can be used as three-dimensional scaffolds. The highly integrated electrodes and circuit systems were located within a sheet of paper, making a new possibility to design maximizing the energy storage performance, integrated circuit systems, and significantly decreasing the thickness of the system without external complex structure. According to the researchers this unique platform can circumvent most of the fabrication challenges related to two-dimensional energy storage sheets… read more. TECHNICAL ARTICLEÂ
