Determination of thermal conductivity of tissue mimicking gel

Abstract

Determination of thermal conductivity of tissue mimicking gel by varying the concentration (0.6%, 1.4%) and temperature from 60⁰C - 80⁰C to find the thermal conductivity by means of setup designed by us. The setup was calibrated and the distance of each thermocouple wire was fixed. It is found that the thermal conductivity is dependent on both the concentration as well as the temperature. The thermal conductivity of water agarose gel decreases with increase in the concentration and increases linearly with increase in the temperature. The proposed experimental set up is novel and simple which provides the reasonable value of thermal conductivity. To mimic biological tissues, the sample is prepared with a concentration of 0.6% (w/v) and 1.4% (w/v) of agarose in water.
