Abstract

We report here a facile, green and cost-effective fabrication of high-performance capacitive pressure sensors by drawing loop-and disc-shaped graphite electrode arrays on copying tissues. Graphene oxide enhanced foam-like paper is prepared as an efficient dielectric layer. The paper-based capacitive pressure sensor enables sensitive detection of finger touch, motion and proximity.
