I am working on fluidic self-assembly of microdevices. The proposed work involves unique micropart face orientation at two liquid interface, distributing/separating parts in well controlled 2D arrangements utilizing waves or other agitation mechanisms, and assemble them onto templates with patterned wettability.
Figure 1: Microchips with distinctive hydrophilic/hydrophobic properties are distributed at PFD/water interface with uniform face orientation by vibration agitation.
Figure 2: Floating microchips are assembled to patterned substrate from PFD/water interface.
