Preparation of graphene-based sensor and its application in human behavior monitoring

Abstract

Graphene-based Nano-sensor has the characteristics of short response time, high conductivity and recoverability. In this work, graphene coated glass fiber sensor and graphene film sensor were fabricated by pressing and oxidation-reduction method, respectively. Graphene coated glass fiber sensor was used to test the pressure of blood pressure and weight. Graphene film sensor was used to test the bending of human fingers, elbows and knees. The results show that the conductivity of the graphene coated glass fiber sensor is 23 260 S m−1, and that of the graphene film sensor is 20 000 S m−1. Both graphene-based sensors have good linear relationship with external load and deformation, and can be used for real-time monitoring of human behavior.
