Paper Electronics: Rough-Surface-Enabled Capacitive Pressure Sensors with 3D Touch Capability (Small 43/2017)

In article number 1700368, Taeyoon Lee, and Wooyoung Shim, and co-workers propose a fundamentally simple method of fabricating capacitor arrays, that can outperform their costly counterparts, manufactured via microfabrication. The capacitor array, made by ubiquitous activity from our daily lives, namely, writing on a paper with a pencil, is used as a pressure sensor, which is further integrated into a fully functional touch device as a principle demonstration of the concept of omnipresent electronics.
