Abstract

See full text

Sensors including thermal load sensors and chemical or biological load sensors, and methods of making the sensors, are disclosed. The sensors may include a solid polymeric matrix and at least one organic indicating material encapsulated within the solid polymeric matrix, wherein the organic indicating material is configured to diffuse into the solid polymeric matrix at a phase transition temperature of the organic indicating material, and wherein an extent of diffusion indicates a target load on the sensor. The target load may, for example, be a thermal load, or a chemical or biological load.
