Polymer Based Microfluidic Components for Bio-medical Applications
Microchannels, micropumps and micromixers are integrated into a single chip fabricated by micro molding replication technique. This optically transparent and biocompatible microfluidic system will enable novel applications in biomedical/chemical analyses, drug delivery, and fundamental studies on microfluidic flow field based on microscopic visualization.

MEMS Fabrication and Assembly

Non-Contact Batch Micro-Assembly by Centrifugal Force
Centrifugal force is applied on micro mirrors for batch assembly. Theoretically, centrifugal force can be generated on different sizes of MUMPs structures (poly1, poly2, and gold) by changing the angular velocity of a spinning disc.
