Microelectrode Arrays Myeongkyu Lee and colleagues fabricate angle‐insensitive mechanochromic sensors on flexible polydimethylsiloxane substrates in article number 2100118. These sensors have a planar Fabry‐Perot resonator structure and can be stretched up to strains larger than 100%. Remarkably, the developed sensors are highly responsive to mechanical stimuli and can facilitate visual detection of localized failures in engineering structures, and are promising for real‐time structural health monitoring.
