“…Using this strategy, many electronic devices—such as batteries, supercapacitors, actuators, heaters, or sensors—have been made of percolation networks composed of nanowires, nanotubes, microflakes, conductive polymers, or elastomers, with the attractive characteristics such as high transparency, high conductivity, and high intrinsic stretchability. [ 16–23 ] On the other hand, structural innovations are inclusive to a wider selection of materials, as traditional nonstretchable materials or components can simply adapt the specially designed structure to achieve device‐level stretchability. Nonstretchable materials, such as metals, oxides, semiconductors, and composites, or rigid components, such as electrodes, sensors or integrated circuit chips, can thus be readily transformed into stretchable devices after adapting wrinkles, arches, serpentines interconnections in island‐bridge structures, or kirigami structures, with little to no sacrifice in their performance.…”
