• Fabrication strategies that pursue “simplicity” for the production process and “functionality” for a device, in general, are mutually exclusive. Therefore, strategies that are less expensive, less equipment‐intensive, and consequently, more accessible to researchers for the realization of omnipresent electronics are required. Here, this study presents a conceptually different approach that utilizes the inartificial design of the surface roughness of paper to realize a capacitive pressure sensor with high performance compared with sensors produced using costly microfabrication processes. This study utilizes a writing activity with a pencil and paper, which enables the construction of a fundamental capacitor that can be used as a flexible capacitive pressure sensor with high pressure sensitivity and short response time and that it can be inexpensively fabricated over large areas. Furthermore, the paper‐based pressure sensors are integrated into a fully functional 3D touch‐pad device, which is a step toward the realization of omnipresent electronics. High‐performance paper‐based pressure sensors are developed through inartificial design of the surface curl and roughness of paper and graphite. The proposed approach involves writing on paper with a pencil, and the sensors can be inexpensively fabricated over a large area. The paper‐based pressure sensors are integrated into a fully functional 3D touch‐pad device, which is a step toward the realization of advanced paper electronics.
