This miniature, thin film embedded thermoelectric generator (eTEG™) converts heat directly into electricity. Ideal for waste heat conversion applications, the solid state eTEG delivers power generation densities (>5W/cm²) in excess of those achieved using bulk materials and is optimized to provide power in a form factor that can be as much as 20x thinner than bulk material alternatives. This opens up new waste heat energy conversion applications for the Nextreme technology as well as remote power applications. 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.
In environments where a lot of heat is available, the device generates power levels of up to 260mW with devices that are not much bigger than a piece of confetti. In low grade thermal environments, the eTEG generates micro-watts of power – enough thermal energy conversion to power remote sensors and other distributed devices.
Nextreme’s eTEG has demonstrated output power levels of >80mW at ΔT of 70°C and >236mW at ΔT of 120°C. With modules measuring just 1.5mm x 2.5mm, the eTEG has corresponding output power densities of ~ 5W/cm².
Nextreme’s eTEG devices generate 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.
