About the Project

Karlsruhe Institute of Technology (KIT) – The Research University in the Helmholtz Association creates and imparts knowledge for the society and the environment. It is our goal to make significant contributions to mastering the global challenges of mankind in the fields of energy, mobility, and information. For this, about 9.800 employees of KIT cooperate in a broad range of disciplines in research, academic education, and innovation.

The Institute of Microstructure Technology (IMT) offers from July 1, 2024 or later, limited up to 3 years, a

PhD Position, research assistant (f/m/d) on on solid-state elastocaloric cooling

Part time 75 %

You will develop a next-generation high-performance elastocaloric cooling device using microfluidics-based shape memory alloys. Our goal is to upscale the cooling capacity of the device, transitioning from microwatts (mW) to several hundred watts (100 W), while simultaneously enhancing temperature lift to unlock new avenues for sustainable cooling application. The project holds particular relevance for various applications, encompassing battery thermal management in electric vehicles, the cooling of critical electronic components, as well as ensuring the safe transport of perishable goods.

You have the following tasks:

  • Design and fabricate microchannels within superelastic SMA materials
  • Characterization of superelastic shape memory alloys (mechanical, thermal, fatigue life)
  • Modelling, design and simulation (FEM multiphysics, lumped element modelling)
  • Rapid prototyping (optical lithography, 3D printing, laser technology)
  • Development, characterization and control of cooling demonstrator variants
  • Simulation-based design optimization

The activity offers the opportunity for a part-time doctorate.

The institute is equipped with an expansive array of state-of-the-art facilities, including a 600 m² clean room, advanced rapid prototyping capabilities like lithography, 3D printing and laser cutting, construction and connection technology labs, as well as various metrology laboratories.

This position is funded by the Hector Fellow Academy (HFA). As a recipient of this funding, you will have the opportunity to engage in various activities within the HFA, including participation in the yearly symposium, in the networking and training events, and in an annual management module of the Hector School.
