Flexible electrodes have applications in things like health and wellness sensors or flexible tablets. These applications usually require the material to bend, but other applications may depend on the ability of an electrode to withstand entirely different mechanical strains. Beyond bending, flexible electronics can also be designed to fold, twist, or stretch.
Stretching is the most stressful, which makes it very challenging to design electrodes that hold up to it. Many applications require cyclic stretching and relaxation, and this can result in material fatigue. If you want flexible conductors that are also transparent, the design specs become even more limiting. Several flexible, transparent conductors exist, but they’re limited by cyclic fatigue or a low maximum strain.
Recently, a team of scientists demonstrated that a gold nanomesh could be combined with a polymer to improve stretchability and eliminate strain fatigue.
