A research team has created colloidal crystals sensitive to time and temperature that look like opal nanostructures and can make new sensors. These sensors record the temperature in their environment visibly and continuously over a set period. As a result, they’re ideal for continuous monitoring of temperature-sensitive processes.
Exposure to only moderate temperatures for long periods is critical for the safe operation of modern high-performance batteries. Short-term temperature increases can jeopardize the battery’s safety and service life. The new sensors, sensitive to time and temperature, can monitor compliance with uniform ambient temperatures successfully. Furthermore, the sensor is already pre-programmed due to its material composition: it operates independently, unaltered later.
The researcher designed a sensor that can detect time and temperature without complicated circuitry or specialized measuring equipment. Furthermore, the artificial crystals they created are a new class of materials with a lot of potential for fundamental research. Researchers may be able to use these colloidal gradients to track down hitherto inaccessible physical events.
