Figure 8.

Flexibility and stretchability of the AgNW electrode embedded in PDMS where (a) shows the change in sheet resistance during the cyclic bending (radius = 3 mm) for various pressure conditions (detailed resistance changes for each condition can be found in Figure S2, Supporting Information); (b) an optical image of an Ag nanomesh skin electrode, invisible to the naked eye, obtained by attaching 2D Ag nanomesh-embedded PDMS to human skin; (c) the change in sheet resistance of the AgNW-embedded PDMS before (with the 3D AgNW network) and after (with the 2D Ag nanomesh) pressurizing at 2000 N/cm², measured as a function of stretch strain; (d) the effect of repeated stretching and releasing on the resistance (stretch/release cycles of tensile strain = 20%, 40%, and 60%).
