Micro ElectroMechanical Systems (MEMS)
is one of the fastest growing research field all over the world [1,2]. Thanks
to the hard-working of many MEMS researchers all over the world, traditional
MEMS has moved from pure academic research field [3] into one mature technology
in industry [4]. Recently, MEMS research has gradually moved into two new
frontier areas: bio-MEMS
and Nano Electro-Mechanical System (NEMS). MEMS/NEMS has attracted researchers
from a variety of disciplines including mechanical engineering (fluid
mechanics, solid mechanics, heat transfer, manufacturing), electrical
engineering (solid-state electronics, integrated circuit engineering) and basic
science such as physics, chemistry and biology. At HKUST, our research projects
are currently focusing on micro/nanofluidics
(micro chaotic mixer, micro/nano electrokinetic flow) and bio-MEMS (micro/nano
capillary electrophoresis chip, micro electroporation chip, micro/nano bubble
actuator to enhance bio-reaction).
