Highly sensitive and flexible tactile sensor with truncated pyramid-shaped porous graphene/silicone rubber composites for human motion detection

This paper presents a novel highly sensitive and flexible tactile sensor based on the fabrication of truncated pyramid-shaped porous graphene nanoplate (GNP)/silicone rubber (SR) composites as the sensing material. The designed tactile sensor has 3 × 3 (=9) sensing units, each unit has three layers: top cover layer with upper electrodes, middle truncated pyramid-shaped porous composite sensing materials, and substrate layer with bottom...
