MICROSENSORS USING NANOSTRUCTURED MATERIALS

Faculty Mentors: Profs. H. J. Cho and S. Seal

Research Description

Recent advances in nanotechnology provide novel functions and applications to microsensors. For successful implementation of microsensors with integrated nanomaterials, various aspects of investigation including design, fabrication and characterization of devices is necessary. As the downsize scaling progresses, the interface becomes more crucial to the field of nanotechnology, where nanoscale objects must generate signals or motions that the macro world can interpret into meaningful data. Micromachining can be used for bridging the two worlds together in the scale and function. The interdigitated sensor electrode with nanostructured material in Figure A shows an example of actual implementation.

The undergraduates will be involved in:

• Learning sensor design and fabrication.
• Basic training on material processing including coating, patterning and annealing.
• Packaging and testing of sensor.
