This study proposes a method to estimate thermal conductivity and thermal diffusivity using a thermoelectric device and a thermographic camera. The experimental results were compared with others literatures. Three different materials including acrylic, apple, and potato were tested. The proposed method has proved to be effective. The experimental results for all selected materials are in comparable range with literature values. The proposed method can be a useful tool for determining thermal properties of solid biological materials with low thermal conductivity and diffusivity values.
