Alexander Zettl
2005
This report describes the localized synthesis, orientation, assembly and application of carbon nanotubes. Synthesis by chemical vapor deposition is activated by means of resistively heating a MEMS structure in a room temperature reaction chamber. Catalyst nanoparticles, created by heating a thin film of NiFe (80%-20% by...

2004
The introduction of commercial foil-strain gauges in the 1950s revolutionized the study of structural and mechanical engineering, as well as material science. These sensors provide an unprecedented window into the fundamental behavior of materials and solids. Coupled with the advent of inexpensive computing power, strain gauges allow engineers to monitor the behavior of structures in the field easily. Refined over the years, the basic foil gauge now meets the demands of a vast array of...

Packaging and Assembling Microfluidic Devices via Plastic Injection Molding

2006

A silicon based microfluidic device has been assembled, encapsulated, and packaged with fluidic and electrical interconnects via plastic injection molding. A microbubble generator was chosen as the test piece for this packaging scheme. It consists of a straight channel etched in silicon and a Pyrex® cover. Gold traces on the Pyrex® allowed for bubbles to be generated by either electrolysis or boiling. The device was subsequently loose assembled in an...

2008
A highly-integrated polymer-based microfluidic device for disposable applications is presented. This device is plastic injection molded and exhibits three levels of integration. First, fluidic interconnects are monolithically formed with the device, enabling robust manufacturing and high-pressure operation (>500 psi). Second, a metal layer is lithographically patterned in the form of microheaters. Finally, a thermally-sensitive hydrogel valve is integrated into the channel. The valve is...

2010
Thermal infrared detectors based on MEMS bimorph beams have the potential to exceed the performance of current uncooled thermal infrared cameras both in terms of sensitivity and cost. These cameras are part of a rapidly growing industry are used for a vast array of applications such as military and civilian night vision, industrial monitoring, and medical imaging. Many researchers have explored the use of metal-ceramic MEMS bimorphs...
