TEC Microsystems - Miniature Thermoelectric Coolers and Sub-Assemblies

Starting from 2013, TEC Microsystems GmbH provides complete analysis, development and manufacturing of thermoelectric modules for Small Scale Energy Harvesting.


The existing experience and advanced technologies allow manufacturing efficient miniature thermoelectric generators for small-scale energy harvesting projects. Tiny thermoelectric generators harvest waste heat and convert it to usable DC power. Small and high heat-to-power conversion ratios make thermoelectric micro-generators perfect to power stand-alone wireless sensors, wireless sensor networks, or wearable devices. Miniature thermoelectric generators provide battery-free, long-lifetime and maintenance-free power supply solutions for many application areas.


HD Technology thermoelectric generators are based on High-Density pellets placement technology. Compared with standard TEGs, the distance between pellets (BiTe posts) inside our HD thermoelectric generators is reduced twice or even more. Higher density means it's possible to fit considerably more BiTe pellets on the same TEG size. Or to reduce the dimensions of the thermoelectric generator without performance changes. Assuming that every BiTe couple inside TEG creates around 400uV/deg electromotive force, HD technology increases the thermoelectric generator output more than twice compared with standard solutions.

Thermoelectric harvesting is considered a key component for many modern and potential future technological applications, like wireless sensor networks, medical body-worn sensors, multi-purpose self-organizing autonomous (micro-)systems, Industry 4.0+ components, etc. Thermoelectric micro-generators have several key features and advantages: small sizes, simple scalability, construction with no moving parts and a very long operational lifetime – tens of years without maintenance. And the unique property – the possibility to convert heat into electricity from very low-temperature differences, just a few degrees. Such temperature differences are naturally present in many everyday things and environmental conditions around us, from the human body's heat to natural temperature fluctuations in soil or water within 24 hours.

ADVANCED TEGs (HD TECHNOLOGY)

MAIN APPLICATIONS FOR TE GENERATORS

◻ Increased TEG voltage and power output

◻ HD and Advanced HD assembly technologies

◻ Up to 1200 BiTe pellets per cm2 density

◻ Standard and thin ceramic materials

◻ Possible TEG customization

◻ Possible integrating with Customer electronics

◻ Wireless Sensors and Transmitters

◻ Wireless Sensor Networks (WSN)

◻ LED Lighting

◻ Battery Charging

◻ Power Supply for IoT

◻ Alternative for replaceable cell batteries

With existing achievements and high-performance bulk technology thermoelectric materials, each couple inside the thermoelectric module generates 400uV/K, almost twice more than widely advertised thin-film technology thermoelectric generators.


It's possible to create tiny thermoelectric generators to provide milliwatts of electrical power from just a few degrees of the temperature difference and up to several watts at a higher dT level. The latest thermoelectric modules assembly technology achievements allow manufacturing micro-generators as thin as 0.6 - 0.7mm by height.
