Construction of Graphene-Paper Flexible Pressure Sensor

Abstract Combining with flexible materials, two-dimensional nanomaterial graphene can effectively improve the mechanical and electrical properties of composites for flexible sensors, which has broad application prospects in health monitoring and human wearable devices. Here, we designed a sandwich paper-based flexible graphene sensor. The amplification and circuit were constructed to realize the acquisition and display of voltage signals caused by micro-strain to achieve the purpose of pulse signal detection. The qualitative and quantitative fabrication process parameters studies were conducted through experiments to make the sensor have high conductivity and sensitivity.
