Laird Technologies Inc. has unleashed its thin film energy harvesting products that the company said transform waste heat to usable output DC power. The eTEG series are thermoelectric power generators that are geared for wireless sensors, LED lighting and battery charging applications.

There are three standard eTEG modules available include the 33mW PG09,14,F0,0102,GG; the 90mW PG24,48,F2,0202,GG; and the 130mW PG37,72,F2,0203,GG.

Laird eTEG series

eTEG series. Miniature energy harvesting devices that can be embedded into many types of applications requiring low output power.

Laird Thermobility Series

Thermobility series. Self-contained thin film thermoelectric power generators that harvest waste heat and convert it to usable output DC power.

The thin film energy harvesters claim to feature micro scale size and higher output power density, and 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 0.6-2.5V in an open circuit at maximum temperature differentials.

There are two products available for trial. These are the WPG-1 that feature up to 1mW output power�and the WPG-1S that feature up to 50mW output power.

According to the company, the devices can be used in remote or mobile settings where a hard line is difficult to install. Many applications in petroleum and gas, commercial infrastructure, transportation and medical instrumentation that use wireless sensors to monitor temperature, composition or flow rate of gases and liquids will find value with integrating these products into their power source requirements, noted Laird.
