Laird Technologies has today announced the release of its new eTEG Series Thin Film Energy Harvesting product line. The eTEG Series are thermoelectric power generators that harvest waste heat and convert it in to usable output DC power. Due to their micro scale size and higher output power density, these devices are especially suitable for use in wireless sensors, LED lighting and battery charging applications.

There are three standard eTEG modules available:
•PG09,14,F0,0102,GG - 33 mW
•PG24,48,F2,0202,GG - 90 mW
•PG37,72,F2,0203,GG - 130 mW

“The eTEG Series are miniature energy harvesting devices that can be embedded into many types of applications requiring low output power.” said Andrew Dereka, Laird Technologies Product Manager. “Because of their sold state reliability and no maintenance requirements, they are suitable to replace energy storage devices or provide power in remote places where access to a power line does not exist. This reliability means maintenance technicians do not have to replace batteries on remotely installed wireless sensors that monitor temperature, flow rate or composition of gases and liquids.”

The Thin Film Energy Harvesters are assembled with thin film semiconductor material, thermally conductive aluminium nitride ceramics and gold plated wire bondable pads. The three models have output voltages from 0.6 to 2.5 volts in an open circuit at maximum temperature differentials.
