eTEG Power Generation Evaluation Kit Eliminates Need for Sophisticated Laboratory Set Up

(Nanowerk News) The eTEG Thermoelectric Power Generation Evaluation Kit provides customers with an easy to use first evaluation solution for assessment of Nextreme's power generation technology. The kit eliminates the need for a sophisticated laboratory set up and requires only modest equipment to measure the power generated by Nextreme’s eTEG UPF40 devices.
Nextreme's thin-film embedded thermoelectric generator (eTEG™) generates electrical power via the Seebeck effect, where electricity is produced from a temperature differential applied across the device. The Nextreme advantage is a very thin, nano-engineered material that delivers a Seebeck coefficient greater than conventional thermoelectric material. The ability of Nextreme’s thin-film thermoelectric materials to convert waste heat into electrical energy using a thin, nanoscale form factor positions it uniquely to address market opportunities that standard bulk thermoelectric devices and other energy scavenging or energy reclamation systems cannot address.
The evaluation kit includes a thick film heater as the heat source, an embedded eTEG UPF40 power generator module, a heat sink/fan assembly and thermocouples for temperature measurement. See Figure 1 below.

The kit provides the full thermal path - from heat source to heat sink - and requires only a power supply for the heater and a volt meter to measure the voltage generated by the eTEG across a load resistor; thereby determining the power output. Customers can easily reproduce and confirm the performance data provided by Nextreme during this evaluation process.
Because customers are used to handling much larger devices, the first evaluation of our power generator is often a challenge. With the new kit, customers essentially plug it in and start evaluating the technology for their application. The kit facilitates the introduction and evaluation of our technology quickly and easily and lowers the barrier and costs for evaluation.
Nextreme engineers are currently working with customers in a variety of industries and applications. These include powering gas sensors from waste heat; trickle-charging batteries in dark places; and improving the fuel efficiency in automobiles.
The eTEG Thermoelectric Power Generation Evaluation Kit is available for $295 and encouraged for first time evaluations. Pricing for individual modules and volume orders is available upon request.
