KiriTEG Project - A Novel, Flexible and Lightweight Thermoelectric Device


European Thermodynamics is excited to share the news of a successful and fruitful collaboration with Queen Mary University of London in KiriTEG project (funded by Innovate UK). After almost 2 years of research and testing different routes for energy harvesting systems for remote sensors and IoT applications, a novel flexible and lightweight thermoelectric device has been successfully completed.

Current thermoelectric solutions in this area tend to be heavy, expensive and require a range of adaptor plates for different heat sources. In KiriTEG, by using thin film technology and advanced assembly techniques we increase flexibility, maximise voltage output and minimise use of thermoelectric material to reduce weight while still maintaining the power output. This leads to an output of 0.7 mV/g/K, 7 times higher than achieved with a conventional device, enabling simpler integration with electronic systems.

The flexible thermoelectric device is designed to work for a temperature difference of 25oC, for example using standard hot water pipes.

The image below shows an example of KiriTEG thermoelectric thin films deposited on flexible substrates towards novel flexible thermoelectric devices for energy harvesting applications.

This research and the results are entirely due to the innovative thinking, collaboration, and hard work by the excellent scientists at European Thermodynamics Limited and Queen Mary University London.

Finally, the entire project would not have been possible if it had not been for the funding support provided by Innovate UK.
