Thermocouples - Nanotechnology

What are Thermocouples?

Thermocouples are sensors used to measure temperature. They consist of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, it produces a voltage that can be correlated back to the temperature. Thermocouples are known for their wide temperature ranges, durability, and ability to function in harsh environments.

How Does Nanotechnology Enhance Thermocouples?

Nanotechnology brings about significant enhancements in thermocouples by enabling the development of nanoscale materials and structures that improve their sensitivity, accuracy, and overall performance.
