Title: Fabrication of Miniature High-Speed Actuator Capable of Biomimetic Flapping Motions
Corresponding Author: Sung-Hoon Ah
Abstract: Beyond conventional military products, technologies in the defense industry sectors around the globe are integrated and fused with newly emerging technologies such as three-dimensional printing (3DP) and smart material fabrication. Acknowledging these trends, this study proposes a miniature high-speed actuator whose fabrication process entails 3DP, smart materials, and shape memory alloy. The manufactured actuator is 25 mm long and 5 mm wide in and weighs 2.5 g, having the optimal frequency in the range of 35-40 Hz. Force and deformation measurement were also conducted, resulting in the lift force of 0.18 N per second with a bending deformation of 5 mm. …

Title: Precision Cutting and Cleaving of Optical Fiber with Femtosecond and CO2 Laser
Corresponding Author: Ik-Bu Sohn
Abstract: In this study, beam divergence through an optical fiber has been controlled through shaping of the optical fiber tip using a CO2 laser, which make the beam divergence smaller than the conventional diamond wheel cleaving method. Precise length cleaving of an optical fiber inserted in a ferrule using a femtosecond laser has also been investigated with respect to changes of the laser pulse energy. A ribbon fiber composed of 12 optical fibers could be cut precisely at different lengths in a micrometer scale …
