Review ArticleOpen accessEvery word in the titleMEMS Based RF Energy Harvester for Battery-Less Remote Control: A ReviewNoor Hidayah Mohd Yunus, Jahariah Sampe, Jumril Yunas, Alipah PawiThe paper deals with the growing interest of energy harvesting systems due to great development in many new emerging technologies in electronics and telecommunication. The research focuses particularly about rectenna element comprises of antenna, impedance matching and rectifier. The rectenna is applied under Micro-Electromechanical-System (MEMS) technology design use in Radio Frequency (RF) energy harvester. MEMS is a technology of miniaturization … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 19 Feb 2017 · 9,357 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLow-g Area-changed MEMS Accelerometer Using Bulk Silicon TechniqueBadariah Bais, Burhanuddin Yeop MajlisA bulk micromachined accelerometer based on an area variation capacitive sensing for low-g applications was developed. The accelerometer was designed with ribbed-style fingers structure on the movable mass connected in parallel and suspended over stationary electrodes composed of differential comb fingers by means of suspension beams anchored onto the substrate. A folded, rigid truss suspension design with low spring constant … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,630 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleROTATING A MEMS INERTIAL MEASUREMENT UNIT FOR A FOOT-MOUNTED PEDESTRIAN NAVIGATIONKhairi Abdulrahim, Chris Hide, Terry Moore, Chris HillPedestrian navigation especially indoors suffers from the unavailability of useful GNSS signals for positioning. Alternatively, a low-cost Inertial Measurement Unit (IMU) positioning system that does not depend on the GNSS signal can be used for indoor navigation. However its performance is still compromised because of the fast-accumulating heading drift error affecting such a low-cost IMU sensor. This results in a … …Journal of Computer Science, Vol. 10, Issue 12 · 5 Jan 2015 · 8,665 accessesView PDFCite
Research ArticleOpen accessIn the keywordsWellbore Surveying While Drilling Based on Kalman FilteringMahmoud ElGizawy, Aboelmagd Noureldin, Jacques Georgy et al.Problem statement: Oil and gas are global fuels obtained primarily from drilling wells in underground terrestrial reservoirs. Vertical drilling is preferred because of its simplicity and therefore low cost, but subsurface targets can often be procured only by directing the wellbore along predefined non-vertical trajectories. For instance, directional drilling must be employed to reach locations inaccessible to the drilling rig, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,577 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Simulation of Microelectromechanical System Capacitive Shunt SwitchesHaslina Jaafar, Othman Sidek, Azman Miskam, Shukri KorakkottilProblem statement: RF MEMS switch is one of MEMS area that creates devices that have great potential to improve the performance of communication circuits and systems and enables the realization of micro size mechanical switches embedded in electronics devices. The low voltage switches are necessary due to their compatibility of standard IC technology in RF application and microelectronics systems. In … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMicroelectrical Mechanical Systems Switch for Designing Multi-Band AntennaA.H.M. Zahirul Alam, Md. Rafiqul Islam, Sheroz Khan, Muhammad Mahbubur RashidProblem statement: In this study Microelectrical Mechanical System (MEMS) switches were proposed to design a reconfigurable/multi-band antenna to replaced PIN diode switches or semiconductor switches due to lower insertion losses, good isolation, much lower intermodulation distortion, and lower power consumption. The antenna is able to operate at very high frequencies. Approach: A reconfigurable antenna that is capable to operate at … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 6,687 accessesView PDFCite
