Mechanism of CNTs-enhanced mechanical properties in GNPs network in comparison with the respond of pristine CNTs and pristine GNPs network to repeated mechanical load. Schematic illustration of the microstructural evolution of CNTs (a) and GNPs (b) and GNP-CNT hybrid (c) under stretch and release. (d) Measurement scheme of strain sensor based on GNP-CNT hybrid. (e) Cross-section of GNP-CNT hybrid sensor, showing stacking GNPs and CNPs before (eI) and after (eII) stretching. Resistance between conductive elements increases after stretching as the disconnections of GNPs and CNTs increase.
