Thermospectroscopic imaging is MIR range imaging technique that enables simultaneous detection of the thermal emission and the transmission or reflection spectrum distribution. This study provides analysis of thermal properties of phase changing material (PCM) composed of alkane compounds in textile-replicated MEMS structures. The technique can determine the heat diffusion process and the structural change at the same time, and it is profitable especially for the dynamic process, such as the phase transition.This study provides analysis of thermal properties of phase changing material composed of an alkane compound. The investigation is centered on understanding the transmittance and absorption of the PCM, which are crucial for its application in thermal management systems. Infrared (IR) spectroscopy and thermal imaging method is utilized for simultaneous measurement of IR transmittance spectra and thermal images, allowing for the observation of the thermoregulation effects of the PCM. Moreover, the thermal diffusivity of the PCM is measured using method temperature wave analysis (TWA), a novel technique that offers precise quantification of the rate at which heat spreads through material. This measurement is critical for determining the PCM’s effectiveness in applications requiring rapid heat absorption and release.
