Shape Memory Alloys

Shape Memory Alloys (SMA) exhibit remarkable features, including the ability to return to a predetermined shape upon heating (shape memory effect) and extensive reversible deformation and thermal changes with stress (superelastic effect). Our focus is on characterizing the mechanical, thermal, and microstructural behaviors of SMAs

 

Elastocaloric Cooling and Heating

Elastocaloric cooling is an emerging cooling technology based on stress-induced thermal changes in shape memory alloys. This approach exhibits no environmental impact associated with leakage of the solid refrigerant, and is highly efficient. Our lab focuses on research, design, development, and prototyping of high-performance elastocaloric cooling devices.

 

Solar Heating and Cooling

Our lab conducts techno-economic analyses for solar-based systems for heating, power generation, and/or cooling applications, with a focus on evaluating photovoltaic, photovoltaic-thermal, and solar thermal technologies.

 

Thermoacoustic Technology

Thermoacoustic technology harnesses the interaction between temperature variations and acoustic waves to achieve energy conversion. Our research covers thermoacoustic heat pumps, refrigerators and power generators, as well as multi-mode systems.

Carl Zeiss Foundation
Dr. Jingyuan Xu from the IMT, KIT was successful with her project at the Carl Zeiss Foundation.

As part of the CZS Nexus program, she will head young investigator group and receive around 1.5 million euros for a period of five years. Dr. Xu is investigating the development of CO₂-neutral elastocaloric cooling devices that are powered by heat and represent an electricity-free alternative. The focus is on cooling in the miniature range, for example, electronic chips or temperature control of bioanalytical chips. At the same time, Dr. Xu would like to lay a foundation for future climate-neutral cooling devices in the macro sector.
