Colorimetric Detection of Mechanical Deformation in Metals using Thin‐Film Mechanochromic Sensor (Adv. Mater. Technol. 10/2021)

Detecting Mechanical Deformation A colorimetric method for detecting mechanical deformation in metals is presented by Myeongkyu Lee and coworkers in article number 2100479, which uses the color change in an attached thin-film mechanochromic sensor. This method enables full-field strains to be mapped by capturing the sensor image using a smartphone and analyzing its color components. The presented colorimetric approach is promising for the structural health monitoring of metallic engineering structures.
