Fluid-mediated parallel self-assembly of polymeric micro-capsules for liquid encapsulation and release

Fluid-mediated self-assembly is one of the most promising routes for assembling and packaging smart microsystems in a scalable and cost-efficient way. In this work the pairwise fluidic self-assembly of 100 mm-sized SU-8 cylinders is studied with respect to two driving mechanisms

(a) Schemes of possible assemblies with flat–fat or flat–rounded components. (b) Histogram of chain length for self-assembled cylinders with flat–fat and flat-rounded extremities. (c) Optical images with schematics after self- assembly of the cylinders.
