Colorimetric temperature sensors are prepared from photo‐crosslinkable polymers by sequentially spin‐coating and crosslinking alternating layers of poly( N ‐isopropylacrylamide) and poly( para ‐methyl styrene). Layer thicknesses and copolymer chemistries are chosen to provide robust colorimetric temperature sensors that cover nearly the full visible spectrum.
