Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible structures that combines the concepts of cilia (flexible elastic elements) and rectifiers (e.g., Tesla pump). We ...

Micro hot embossing on a large area polymeric substrates using roll-to-roll (R2R) mode has been considered as one of the most promising technologies that can offer continuous fabrication of large area polymeric substrates. Besides continuous operation, roll-to-roll (R2R) process offers advantages such as low forming load and higher replication accuracy. Consequently, R2R embossed polymeric ...

Computational Analysis of Evaporation in Tailored Microchannel Evaporators

S. Arslan[1], J. Brown[1]
[1]Lawrence Technological University, Southfield, MI, USA

The rapid increase in power densities of integrated circuits has induced a significant interest in new reliable and high heat flux cooling technologies. The implication of such growth is the increased need for more efficient and more compact cooling mechanisms. Promising research has been conducted in the area of MEMS cooling devices, taking advantage of the increased heat transfer ...

Investigating the Use of a Piezoelectric Actuator for the Appendages of a Microrobot

J. Clark, and J. Clark
Purdue University, West Lafayette, IN, USA

We investigate the use of a piezoelectric actuator for the appendages of a microrobot. Possible uses may include micro assembly, mobile surveillance, etc. What is different about this microrobot is that it uses 2 degrees of freedom, low powered piezoelectric flexures, while attempting to mimic the maneuverability of an ant-like insect. In the paper, we use COMSOL to characterize this type of ...
