Polymeric Thermoelectric Sheet Evaluation System ZEM-d series

 
This system can measure Seebeck coefficient and electrical resistivity in the thickness direction and also evaluate the thermoelectric properties on anisotropic materials at the same measurement direction.

Features

  • It is possible to evaluate the Seebeck coefficient and electrical resistivity in the thickness direction with generating temperature difference.
  • Automate the V-I plot measurement for determining the contact condition of the lead wires when setting a sample and set the optimum current.
  • It is also possible to measure the in-plane direction for a flexible sheet sample.(Optional)

Applications

  • Evaluation of the thermoelectric properties in the thickness direction of organic and inorganic thermoelectric materials
  • Evaluation of the anisotropy of flexible materials
