Thermoelectric power generator microelectronics for aerospace and sensor applications introduced by Nextreme

DURHAM, N.C., 17 Nov. 2010. Nextreme Thermal Solutions Inc. in Durham, N.C., is introducing the eTEG HV37 thermoelectric power generator that converts waste heat into electrical energy for a variety of self-powered applications in the aerospace, wireless sensor, automotive, industrial, and medical device industries.

The eTEG HV37 can produce 1 milliwatt of output power and an open circuit voltage of 170 millivolts in a size of six square millimeters. The module is six millimeters high, and can be configured electrically in series to produce higher voltage and power outputs. Nextreme's eTEG devices generate electricity via the Seebeck effect where a voltage is produced from the temperature differential produced by heat flow through the device.

"Deployment of distributed sensors and sensor networks have led to an increased interest in renewable and autonomous power sources," says Dave Koester, vice president of engineering at Nextreme. "The use of waste heat is an attractive source of energy for many applications."

The high voltage output of the HV37 is enabled by Nextreme's proprietary micro-scale thermoelectric technology. Applications such as generating power off the heat of the human body, or generating power for wireless sensors require a high density of thermoelectric elements in order to generate power at low temperature differentials. Nextreme's patented thermal bump fabrication process can achieve thousands of elements per square centimeter.
