Fatigue-free, superstretchable, transparent, and biocompatible metal electrodes
Abstract
Fatigue is a deadly disease for metals. Fatigue often happens under cyclic loading even if the strain level is low. However, a stretchable transparent electrode, which can be made of metal and is a key element in stretchable electronics, needs high stability at large strains. Here we show that Au nanomesh on a slippery substrate is fatigue-free when cyclically stretched to large strains (>100%). Moreover, cells can grow on the Au nanomesh. A metal mesh that conducts electricity, is biocompatible, and is completely free of fatigue will be an ideal electrode not only for flexible electronics, but also for implantable electronics.
