(a) The finite element analysis (FEA) model structure (top) and the computed stress concentration factors (SCF) against the loading tensile strain (bottom) of isolated UGCM (black curve) and the UGCM assembled in between two rubber layers (orange curve), respectively. The SCF is defined as the ratio of max principal stresses distributed at the ends and the middle area. (b) Schematic shows the key construction of the assembled GP-laminate of UGCM with in-built grooves on PDMS layers. A UGCM panel was sandwiched into the groove formed by two PDMS layers. The two ends of the UGCM were separately connected to two soft conductive wires via Ag-pastes. (c)Relative change in resistance of the GP-laminate being stretched to varying levels of strain: 10% (green), 25% (light green), 50% (yellow), 75% (orange) and 100% (red) respectively, indicating its good stretchability and sensing ability. △R refers to the resistance changes of the GP-laminate under the specific strain and R0 refers to the base resistance of the GP-laminate before stretch. (d)The GP-laminate with highly flexibility.
