AI Technical Summary
Existing temperature-sensitive products lack a reliable and direct method to indicate the exposure to a specific temperature threshold, which can compromise their quality and safety, such as vaccines and food products, the existing temperature-sensitive products lack a reliable method to indicate exposure to a specific temperature threshold, which can affect their quality and safety.
A temperature sensor that includes a color-changing system comprising a dye, a developer, and a solvent, where the interaction between the dye and the developer results in a visible color change upon exposure to a preselected temperature threshold, with a color-memory property to retain the color change.
The temperature sensor effectively indicates exposure to a specific temperature threshold, providing a direct visual indication of thermal history, ensuring the quality and safety of temperature-sensitive products.
