A novel method for measurement of thermal conductivity of soft materials and liquids with the polyimide film by utilizing a point contact method has been developed to solve several problems when it was applied to soft materials and liquids. Numerical simulation was carried out to evaluate the effect of the polyimide film. In addition, water, agar, fat and muscle of pig were selected as soft materials and liquids and their thermal conductivity were measured. As a result, the repeatability of measurement was improved by using the polyimide film, but there were differences between determined and literature value of thermal conductivities. A method in this study has a possibility to measure the thermal conductivity of soft materials and liquids by application of sample calibration correcting the bias.
