WebThermoelectric definition, of, relating to, or involving the direct relationship between heat and electricity. See more. WebMar 4, 2016 · Thermoelectrics generate the electricity from the movement of electrons within a metal. Metals are good conductors because electrons can move freely within them, similar to a fluid in a pipe. Heating one end of a thermoelectric material causes the electrons to move away from the hot end toward the cold end.
