Fluid Mechanics of Functional Materials

dr.ir. C.W. Visser (Claas Willem)
Assistant Professor

 

The Fluid Mechanics for Functional Material team creates new materials from scratch. Here, droplets or particles are used as "building blocks" that add functionality to 3D-printed pieces in programmable shapes.

 

Our research focuses on creating the right building blocks and stacking them into the right shape, for example by understanding and controlling the impact of micro-scale droplets [1,2]. Together with collaborators, this strategy has advanced multi-scale tissue engineering [3], rapid fabrication of complex particles for chemical reactions [3,4], and 3D printed micro-sensors in gold and platinum [5,6].

 

Upcoming projects will focus on aero-acoustic materials, thin-film flows, and foams. These projects are pursued in close collaboration with experts who have deep knowledge of the application field, either at the University of Twente, in companies or with (inter)national collaborators.
