Figure 12.3 Metal nanowire hierarchical percolation network electrode for a highly
stretchable metal electrode. (A) Relative resistance change measure-
ment under various strains for a highly stretchable electrode on
pre-strained Ecoflex substrates. The inset graph shows the relative
resistance change for a Ag thin film (purple), short Ag NW percolation
network electrode (blue) and electrode (green) during stretching on
50% pre-strained Ecoflex substrates. (B) Digital pictures of macroscopic
(top row) and microscopic surface morphology (middle row) of an
electrode on a pre-strained Ecoflex during 460% stretching process in
Figure A (green circles). Schematic behavior of the VAgNPN electrode
and an Ecoflex substrate during stretching (bottom row).

electronics. Lee et al. implemented the very long Ag nanowires to realize a
high performance stretchable electrode with a world record strain above
