In an effort to develop a Standard Reference Material (SRM™) for Seebeck coefficient, we have conducted a round-robin measurement survey of two candidate materials—undoped Bi2Te3 and Constantan (55 % Cu and 45 % Ni alloy). Measurements were perfo

A Standard Reference Material (SRM™) for the Seebeck coefficient is critical for inter-laboratory data comparison and for instrument calibration. To develop this SRM™, we have conducted an international round-robin measurement survey of two candi

A prototype energy-harvesting thermoelectric generator (TEG) is being designed, fabricated and tested to provide power for wireless sensors used in health monitoring of Navy ship machinery. TEGs utilize the heat transfer between shipboard waste heat
Hi-Z Technology, Inc. (Hi-Z) is currently developing four different auxiliary generator designs that are used to convert a portion (5 to 20%) of the waste heat from vehicle engines exhaust directly to electricity. The four designs range from 200 Watt

Twentieth Annual IEEE Semiconductor Thermal Measurement and Management Symposium (IEEE Cat. No.04CH37545).
Thermoelectric coolers in use today have a coefficient of performance (COP) of only about 0.5. This compares to COPS of larger scale machines, such as air conditioners and refrigerators at levels of 3.0 to 5.0. For electronic component cooling there
