Laser Micro-Patterning by Means of Optical Fibers with Micro-grinded Lens End Faces




Introduction

Nano-patterning of polymer surface has found a wide range of applications including biotechnology, where holes in the size of hundreds – nm can influence the growth and differentiation of relatively large living cells . Instead of the e-beam patterning technique used in the Ref. 1, we ap-plied direct writing by laser-light. In our previous papers , w ....etc

Demand for the research and development of the micro-manufacturing technologies is being fueled by the ever-increasing trend towards miniaturization over a wide spectrum of disciplines and industries. Recent technological advancement in the defense, biomedical, telecom-munications, consumer electronics have spearheaded the need for micromanufacturing technology, which is now beginning to find application in the automotive and aerospace industries due to the economic potential of the micro-factory paradigm. Micro-scale mechanical manufacturing p ....etc

Abstract


A multidisciplinary team of end users and suppliers has collaborated to develop a novel yet broadly enabling process for the design, fabrication and assembly of Micro-Opto-Electro-Mechanical Systems (MOEMS). A key goal is to overcome the shortcomings of the polysilicon layer used for fabricating optical components in a conventional surface micromachining process. These shortcomings include the controllability and uniformity of material stress that is a major cause of curvature and deformation in released microstructures. The appr ....etc

On the macro scale, feedback control is routinely applied to improve performance and enable new tasks in complex and uncertain systems operating in noisy environments. Our lab has focused on applying feedback control ideas to systems on the micro scale. Here we show how control methods can improve existing performance in the UCLA lab-on-a-chip electrowetting system and can create entirely new capabilities in our 'micro fluidic tweezers' cell steering devices.In the Electro-Wetting-On-Dielectric (EWOD) system developed at UCLA by CJ Kim, a grid ....etc

Hybrid Engines are typically described as engines with two power sources.

A hybrid electric vehicle (HEV) is a type of  hybrid vehicle and electric vehicle which combines a conventional internal combustion engine (ICE) propulsion system with an electric propulsion system.
