The use of a Peltier device in thermal contact with a specimen can provide heat source and sink. The utilization of this equipment is experimented, applying successive heating and cooling stages on various specimens and measuring the temperature outside of the contact area. Oscillating temperature in time and space can provide indication on the thermal diffusivity. The appealing ability of sourcing and sinking heat, with average null effect on temperature, may represent an innovative approach with respect to traditional simulation technique. A simple analytical model is exploited for recovering the inversion equations. Numerical simulation allows to better understand the real proces on the sample.
