Title: Carbon Nanotube Templated Microfabrication

Abstract:

Precision microscale manufacturing, driven initially by the microelectronics industry, has more recently been extended to fabricate structures for mechanical and optical applications. Very low cost microscale mechanical sensors have become ubiquitous; most smart phones now incorporate microfabricated accelerometers and gyros. Silicon is not only the anchor material for microelectronics but vertically etching of silicon is also used to create the three dimensional microstructures used in applications ranging from inertial sensors to neural probe arrays. We have recently developed carbon nanotube templated microfabrication (CNT-M), a fabrication technique that is complementary in several ways to vertical silicon etching. CNT-M enables high aspect ratio fabrication of microstructures from a wide range of materials including ceramics and metals. We now use CNT-M to fabricate structures for applications ranging from energy storage to chemical filtration and detection.
