Figure 6. FEA analysis of sensing performance: (A) configurated model, (B) the calculated stress change of the sensors with different HNT contents at 30% strain, (C) the studied stress changes of HNTs coated with PDA and uncoated with PDA in PDMS under strain, (D) finite element physical model of GO lap-joint, and (E) the gauge factors of the two models in (D) separately calculated.
