ABSTRACT

Thermoelectric technology can be used to generate a small amount of electrical power,

typically in the W or mW range, if a temperature difference is maintained between two

terminals of a thermoelectric module. Alternatively, a thermoelectric module can operate

as a heat pump, providing heating or cooling of an object connected to one side of a

thermoelectric module if a DC current is applied to the module s input terminals. This

chapter reviews the development of micro electromechanical systems !"#"$% based

thermoelectric devices suitable for micro&power generation, heating and cooling

applications. The chapter begins with a brief overview of thermoelectric technology,

macro&thermoelectric module construction and operation. "icro&thermoelectric modules

are introduced, and a review of recent developments in research, commercial

development, and typical application of "#"$ based micro&thermoelectric devices is

made. The chapter draws conclusions on the development and potential application of

"#"$ based thermoelectric devices suitable for thermoelectric cooling, heating and

micro&power generation.
