Thermoelectric Metrology

Metrology, the science of measure, is in constant evolution and development in every field. Recently, due to the energy problem, some physical effect and related device are receiving new attention, in particular: piezoelectricity and thermoelectricity. We think that the time is ripe to expand the science of measure in a new may:Thermoelectric Metrology. This work represent a new beginning in this field: we study and build a new method and instrument to measure the figure of merit zT and Resistance R, also we describe a new way to use thermoelectric device (in particular Peltier cells), to apply linear system theory and frequency analysis to measure thermo-physical property such as thermal effusivity and thermal diffusivity.
