Abstract: As technology advances, so must our methods. One of the most important aspects when working with physical instruments is to maintain heat flow in the desired direction. The hot disk transient plane source is a single unit that produces heat while doubling as a temperature sensor, so it is an excellent way to control and monitor the movement of heat without loss to the environment. The sensors for the hot disk TPS model are made from nickel as it is more resistant, it protects against mechanical damage, and can be used on a variety of samples. However, in this study, silver sensors were more sensitive to lower temperature changes (approximately 50 K) than nickel sensors. Although nickel sensors are used for TPS methods today, exploring the use of other metals in the future could lead to testing samples at a wider range of temperatures.
