摘要: Abstract A two-dimensional random model is developed to investigate the piezoresistive behavior of stacked graphene composites (SGCs). The theoretical value gauge factor caused by flakes sliding determined and it consistent with simulation result. relative resistances, factors morphologies at different strain levels are obtained. These results reveal that sensing properties SGCs come from morphology change flakes. It also confirmed overlapped leads linear characteristics, disconnection brings about non-linear effect. Additionally, influence length graphene, initial resistance pre-stretched treatment on performance investigated. can contribute improvement or innovation for expected performance.
