Fabrication and Characterization of Thermo-pneumatic Peristaltic Micropumps

Liao H-H, Liao W-C, Liao H-H, Liao W-C, Yang Y-J, National Taiwan University, TW

In recent years, the application of microelectromechanical systems (MEMS) technology on biomedical fluidic analysis has progressed rapidly. By minimizing the system, the time of analysis and reaction can be effectively shortened. Also, the quantities of [...]

Morphological, Crystalline and Photo-luminescent Property of Zinc Oxide Nanorod Array Controlled by Zinc Oxide Sol-gel Thin Film

Huang J-S, Lin C-F., National Taiwan University, TW

Our work provides a systematic study of controllable morphology, crystallinity and photoluminescence (PL) of ZnO nanorod array. Our investigation demonstrates that the pre-treatment conditions of the ZnO sol-gel thin-film have strong influences on the morphology, [...]

Experiments and Simulations of Infrared Transmission by Transverse Magnetic Mode through Au Gratings on Silicon with Various Air-slot Widths over the Period

Chen Y-R, Kuan C.H., National Taiwan University, TW

Au gratings with various air-slot widths were fabricated experimentally by electron beam lithography system (e-beam) and their infrared (2.5~25 m) transmission of the transverse magnetic mode (TM mode) were investigated by the Fourier Transform Infrared [...]

Transient Analysis of Snap-through Behavior of a MEMS Optical Switch
