Thermoelectric Effect
  • The PeltierSeebeck effect, or thermoelectric
    effect, is the direct conversion of heat
    differentials to electric voltage and vice versa.
  • The Seebeck effect is the conversion of
    temperature differences directly into
    electricity.
  • The effect is that a voltage, the thermoelectric
    EMF, is created in the presence of a temperature
    difference between two different metals or
    semiconductors.
  • The voltage created is of the order of several
    microvolts per degree difference.
