Graphene oxide (GO) foam exhibits both excellent elastic property and high relative dielectric permittivity, which is a novel building block for future wearable electronic devices. Herein we present an ultra-sensitive GO-based capacitive pressure sensor with graphene as electrodes by an efficient, low-cost fabrication strategy over large-area integration as well as patterning for recording spatial pressure distribution. The GO-based sensor can detect a subtle pressure of â¼0.24Pa with a fast response time (â¼100Â m) and a high sensitivity (â¼0.8Â kPaâ1). The superior sensing properties combining with good flexibility and robustness reveal a great application potential in various fields, such as health monitoring, flexible human-computer user interfaces, and robotics, which also give a new insight for all-carbon electronics.
