New Success Story: Cool BatMan
The aim of the Cool BatMan project was to establish a fundamental understanding of the dynamic thermal behavior of two physical phenomena coupled within a compact magnetocaloric cooling device.
A magnetocaloric material (and the associated magnetocaloric effect) was combined with the phenomenon of electrowetting-on-dielectric (digital microfluidics), resulting in a unique magnetocaloric cooling concept that could in the future serve as a BTMS for batteries in e-mobility. During the Cool BatMan project, we developed expertise in microfabrication technologies, new characterization methods, observations of new physical phenomena and digital microfluidics (EWOD). Although digital microfluidics is well established in biochemistry and pharmaceutical applications, within this project we identified its strong potential for use in entirely different technological and scientific domains—particularly in thermal management at the mini- and microscale.
