PHOTOACOUSTIC MEASUREMENT OF THERMAL EFFUSIVITY AND THERMAL DIFFUSIVITY OF HUMAN SKIN
In recent years, the technical methods related to the heat transfer phenomenon have been increasingly applied in the field of medical technology. And accurate data are required for thermophysical properties of human skin. However, the traditional measurement methods of thermophysical properties for industrial materials are unavailable to human body, so simple, quick and noninvasive measurement technique which puts less strain on human body is required. The present study focuses on photoacoustic methods as a technique which meets above requirements and aims at in vivo measurement of thermal effusivity and thermal diffusivity of human skin. The thermophysical properties of samples were measured for showing the validation of the developed technique. A rigid polyvinyl chloride (PVC) sheet as thin plate and an epoxy resin were adopted as samples. The results indicated the present technique was sufficiently accurate. The measurements were carried out for thermal effusivity and then thermal diffusivity of human skin.
