Thermophysical properties such as thermal conductivity, viscosity, diffusion coefficient, and Sorret coefficient are important parameter for the thermal design of material and can be applied for the process monitoring and design. In this talk, the novel optical sensing technique of these thermophysical properties using the laser-induced dielectrophoresis, and Sorret effect (thermophoresis) are introduced. Furthermore, a novel V-shaped micro mirror using the elector-thermal actuator is demonstrated. Finally, the nanoscale thermometry using the near-field fluorescence is presented.

About the speaker:
Yoshihiro Taguchi received the B.S., M.S., and Ph.D. degrees in mechanical engineering from Keio University, Yokohama, Japan, in 1999, 2001, and 2004, respectively. He was a Postdoctoral Researcher at Stanford University, Stanford, CA, from 2004 to 2006. His research at Olav Solgaard Laboratory at Stanford University was focused on the design and fabrication of a dualaxis confocal fluorescence endoscope and vertical MEMS optical scanner for medical applications. He is currently with Keio University as an Associate Professor in the Department of System Design Engineering. His research interests are in optical MEMS devices using optical manipulation technique, near-field optics, near-field fluorescence, thermoreflectance, and near-field photothermal desorption for property measurements.
