摘要

•With increasing rGO/GNP doping, the resistivity first reduced dramatically and then remained stable.•Under both compressive and tensile loads, rGO/GNP exhibits high piezoresistive repeatability.•The rGO-HO with a high concentration of oxygen and the GNP-L with a large sheet have a lower resistance and a more sensitive resistive response.
