Background:Stirling cycle-based cryocoolers employ mechanical compressors activated by inductive electrical motors producing an oscillating pressure in a gas. The main disadvantage of these conventional compressors is their limited lifetime, caused by mechanical friction and wear. Wear products degr.....

The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. Thermoelectric effects are used in various applications, where heat energy is saved, that would be otherwise lost. Although the TE conversion efficiency is nowadays low (5-8%), the novel.....
