Thermoelectric Generators (TEG)

•  TEG is used to harvest thermal energy and convert to electrical energy – Power generation

•  Utilizes the temperature difference across the TEG system

•  Energy conversion efficiency is low (5-15%)

•  Efficiency improved by proper materials selection

• Temperature difference
• Thermal conductivity
• Electrical conductivity
