Abstract

Flexible electronic technology has laid the foundation for complex human-computer interaction system, and has attracted great attention in the field of human motion detection and software robot research and development. Graphene has high electron mobility, high thermal conductivity, excellent mechanical properties, and is an ideal material for preparing flexible conductive networks. In this study, a simple preparation process of fractal flexible sensor based on graphene ink is proposed. The fractal structure is printed with PDMS graphene ink using Ecoflex 00-30 as the substrate by using direct ink writing method. After curing, it has high tensile and piezoresistive sensing properties. The structure thickness is 2 mm, which is convenient for assembly and adhesion. The sensor has been tested under different bending angles, showing excellent sensitivity and wide response range, and can be used for attitude recognition. In addition, repeatability and good mechanical properties make it have potential applications in wearable devices, electronic skin and soft robots.
