Abstract
The electromechanical properties of single-layer graphene have inspired specific application to force sensors, sinceit is capable of sensing within the range of human pressure perception. In this study, we present a pressure sensor for vertical force that is flexible and transparent by introducing a single graphene layer on a polyethylene naphthalate substrate. This substrate is commonly used as a force absorber in sensors. By employing it with a pressure amplifying structure, the performance of the sensor shows a reliable resistance change of 0.15% per 1 kPa of applied vertical pressure. Detection for the motion of the finger joint and touching are demonstrated with the sensor equipped on the human body.
