eteg HV14 Power generator

Download Data brief

The eTEG HV14 thermoelectric power generator can convert waste heat from thermal sources into usable electricity as an energy source. The eTEG™ HV14 has demonstrated output power levels of >16mW at ΔT of 70°C and >45mW at ΔT of 120°C. With modules measuring just 1.8mm x 1.5mm, the eTEG HV14 has corresponding output power densities of ~ 0.6 and 1.6W/cm².

Manufactured using semiconductor fabrication techniques, the eTEG is scalable, cost-effective, and can be utilized in a broad range of markets and applications including automotive, government and aerospace, thermal batteries, medical implants and wireless sensor networks.

At the core of the module is Nextreme's breakthrough Thermal Copper Pillar Bump, a structure made from thin-film thermoelectric material embedded into flip chip interconnects (in particular, copper pillar solder bumps) used in electronic and optoelectronic packaging. The device generates electricity via the Seebeck Effect, where electricity is produced from a temperature differential applied across the device. The temperature difference (ΔT) between the hot (Th) and the cold (Tc) sources leads to change in the difference of the Fermi energies (ΔEF) yielding a potential difference, which drives a current.

Advantages of the eTEG HV14 thermoelectric power generator for clean energy production include:

  • They are solid-state – there are no moving parts;
  • They contain no consumable materials;
  • They have demonstrated very long operating lifetimes.
  • The eTEG HV14 is RoHS compliant and is available for order now. Pricing is available upon request.
