Thermoelectrics is a promising field challenging to reach wide-scale application in waste heat power conversion, and now especially with a focus on energy harvesting to power IoT sensors and devices. It is necessary to develop high performance materials and industry compatible processes for modules. In addition to bulk modules we are developing thin films and flexible hybrid sheets. There are intrinsic paradoxes in the requirements of physical properties to achieve high thermoelectric performance. In order to overcome traditional limitations we have been developing new principles such as utilizing magnetism; magnetic interactions, spin fluctuation, etc. to enhance thermoelectric properties, discovering new high perrformance materials. Ultra-high performance has also been discovered in the thin film of a related material.
