Thermal Transport Characteristics of Human Skin Measured In Vivo Using Thermal Elements

摘要

Devices and methods useful for sensing epidermal tissue are disclosed. Thermal data from the devices allows for determination of thermal transport properties, such as thermal conductivity, thermal diffusivity and heat capacity per unit volume. From these data, tissue parameters, such as hydration state, stratum corneum thickness, epidermis thickness and vasculature structure may be determined. These parameters may be used, for example, to evaluate the efficacy of dermatological compounds.
