Abstract: The Transient Plane Source (TPS) Technique measures the thermal conductivity, thermal diffusivity, and specific heat of solids and liquids. An electrically conducting double spiral nickel sensor pulses a current through a sample which increases its temperature, while simultaneously recording the length of time it took for the sample to heat up. This study, researchers tested the thermal properties of various materials and determined that anisotropy must be considered when these tests are completed to produce accurate results. The TPS method is being continuously developed to keep up with new technological demands.
