Harnessing cracks in metal films: Design strategies for stretchable conductors

InfoMat, EarlyView.
In stretchable electronics, metal film‐based components function either as strain‐insensitive interconnects/electrodes or as strain‐sensitive sensors, both of which are governed by crack‐induced electromechanical responses, yet these two roles have often been discussed separately in previous reviews.
