23_21/2013Sensors: A Printable Optical Time-Temperature Integrator Based on Shape Memory in a Chiral Nematic Polymer Network (Adv. Funct. Mater. 21/2013)

On page 2723, Albertus P. H. J. Schenning, Cees W. M. Bastiaansen, and co-workers report the fabrication of a printable, optical, irreversible temperature sensor (e.g., a time-temperature integrator) by mechanical embossing of a chiral nematic polymer network, which yields a green colored film. A permanent color shift to orange is observed at temperatures above the glass transition temperature of the embossed film. Cover design by ICMS Animation Studio TU/e.
