This paper describes feasibility of switchable heat storage device, that can switch the thermophysical properties, using solid-solid phase-change thermal storage materials (PCMs). Solid-solid PCMs have some merits compared to solid-liquid PCMs: high thermal conductivity and unnecessary of container. Therefore, the solid-solid PCMs are suitable for micro scale thermal control device. Vanadium dioxide (VO2) is one of the solid-solid PCMs. In this study, the electrical resistance of the VO2 powder was measured under compressive pressure to estimate the phase transition temperature (PTT). As the result, onset PTT and end PTT decreased 2.1°C and 3.5°C under compressive pressure, respectively.
