High-accuracy thermophysical property measurement technique based on Labview-3ω method

Abstract

High-accuracy thermophysical property measurement technique plays a significant role in the development of new materials and structures. Especially with the emerging nanomaterials, techniques that can provide thermophysical property measurement for nanoscale structures become urgent needed. Here, a Labview-3ω technique with automatic data acquisition and thermal measurement functions on the basis of the conventional 3ω technique is developed, which greatly improves the measurement speed, accuracy, and uncertainty for a wide range of nanomaterials. This high-speed, automatic, and intelligent measurement method provides great application potential for a thermophysical property measurement of various materials.
