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
Research ArticleOpen accessIn the abstractIMPLEMENTATION OF ANFIS FOR GPS-AIDED INS UAV MOTION SENSING AT SHORT TERM GPS OUTAGEChot Hun Lim, Tien Sze Lim, Voon Chet KooThe recent improvement in Micro-Electro-Mechanical System (MEMS) technology has enabled the evolvement of Inertial Navigation Unit (INU) to be built on top of a low cost, small size Integrated Circuit (IC) chip. Due to the nature of the MEMS INU, its outputs are normally corrupted by the resided stochastic noise. A common practice to regulate its measurements into usable motion … …Journal of Computer Science, Vol. 10, Issue 12 · 29 Dec 2014 · 8,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Self-Adaptive Neuro Fuzzy Inference System for the Removal of Non-Linear Artifacts from the Respiratory SignalA. Bhavani Sankar, D. Kumar, K. SeethalakshmiProblem statement: In this study, a new ANFIS-based adaptive filter is proposed to remove the non-linear artifacts from the respiratory signal measured using MEMS based accelerometer sensor. The data recorded from the abdomen movement includes the respiratory signal, electromyogram, 50Hz power line interference and the random electrode noise. In order to avoid convergence into local extremes, the system employs ANFIS … …Journal of Computer Science, Vol. 8, Issue 5 · 16 Feb 2012 · 6,891 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch in the Improvement of Wettability of Micro-Structure in Patterned ElectrodepositionLi Guangyang, Wang Hong, Yuan Yang et al.Problem statement: The high aspect-ratio electrodeposition was widely used in the manufacture of non-silicon MEMS devices.
