In this paper, we report the development of micromachining techniques for a biodegradable polymer for the first time. By virtue of their ability to naturally degrade in tissues, biodegradable polymers hold immense promise as new materials for implantable biomedical microdevices. This work focuses on the establishment of microfabrication processes for biodegradable microstructures and microdevic...
This paper reports on the generation of spatially confined plasmas and their application to silicon etching. The etching is performed using SF6 gas and dc power applied between thin-film electrodes patterned on the silicon wafer to be etched. The electrodes also serve as a mask for the etching. The typical operating pressure and power density are in the range of 1–20 Torr and 1–10 W/cm, respect...
switchable metamaterials that possess very different states are almost a necessity. [ 11 ] Most of the tunable metamaterials that have been demonstrated rely on tuning constituent materials or changing surrounding media by introducing natural materials with higher tunability, such as liquid crystals and phase changing materials. [ 12–19 ] However, this limits the choices of materials and become...
The development of ultrafast lasers with higher functionality as a result recent advances in the study light-matter interaction has revolutionized micromachining materials greater accuracy and smaller heat-affected zone. popularity femtosecond industry furthered enhancements to their flexibility efficiency, including different methods operation such FemtoLux 30, enabling new techniques material...
This study introduced a method based on magnetic field assisted finishing mechanism for micromachining the inner surfaces of Aluminum tubes. In this approach, using the alternating magnetic field of an AC electromotor, abrasive particles were formed as Magnetic Rods (Magnetic Clusters) and surface micromachining was carried out by the dynamic particular pattern made by an alternating magnetic f...
Nowadays in highly competitive precision industries, the micromachining of advanced engineering materials is extremely demand as it has extensive application in the fields of automobile, electronic, biomedical and aerospace engineering. The present work addresses the modeling and optimization study on dimensional deviations of square-shaped microgroove in laser micromachining of aluminum oxide ...
