Abstract
A thermometer includes a substrate, a cover layer, and a plurality of voids between the substrate and the cover layer. Each void contains at least one liquid crystal temperature sensing composition. The plurality of voids is arranged in at least one array (e.g., two rectangular arrays). The cover layer is located between the substrate and a biaxially-oriented polyester film. The thermometer may include at least two support layers on a side of the substrate opposite the cover layer and a biaxially-oriented polypropylene film/tape above a portion of the biaxially-oriented polyester film.

A reusable thermometer comprising:
- a substrate comprising PETG;
- an optically transparent cover layer;
- a first support layer on a side of the substrate opposite the optically transparent cover layer;
- and
- a second support layer on a side of the first support layer opposite the substrate;
- a plurality of voids between the substrate and the optically transparent cover layer, each void of the plurality of voids containing a liquid crystal temperature sensing composition;
