Review ArticleOpen accessIn the keywordsMEMS 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
Review ArticleOpen accessIn the keywordsArchitecture of Ultra Low Power Micro Energy Harvester Using RF Signal for Health Care Monitoring System: A ReviewFarah Fatin Zulkifli, Jahariah Sampe, Muhammad Shabiul Islam, Mohd Ambri MohamedThis research presents architecture of Ultra Low Power (ULP) Micro Energy Harvester (MEH) using Radio Frequency (RF) signal as an input. RF has many advantages compared to other ambient sources because it is not affected by changes of weather or time, does not require heat or wind exposure and it can be moved randomly within the bound of the transmission … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 7 Jul 2015 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Mutual Coupling of Typical Commercial UHF RFID Tags in a High-Density EnvironmentGbamélé Konan Fernand, Akpata Edouard, Assamoi Claude Daniel et al.In the context of high-density passive UHF (Ultra High Frequency) RFID (Radio Frequency Identification) tag technology, the problem of mutual coupling has to be taken into account as one of the performance criteria of UHF RFID systems. In practical applications, mutual coupling changes the intrinsic parameters of the antennas attached to these tags, i.e., the impedance matching of the antenna … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 14 Oct 2022 · 6,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation and Optimization of Perovskite Type Micro Thermoelectric GeneratorJeyashree Yesuraj, Vimala Juliet Ashokan, Sukhi Yesuraj, Rebecca Shirly Harrison ChristleyIn this study the thermoelectric properties of perovskite type Ca-Mn-O3 compounds are estimated for the operating range of 850-1150 K. The optimization of design module for maximum power output is obtained using the analytical expression for power of Thermoelectric Generator (TEG). For the optimum length of 1.4 μm and with a cross sectional area of 0.3×0.3 μm the power obtained … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 26 Nov 2016 · 7,381 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Architecture of Maximum Power Point Tracking for Ultra-Low-Power Based Hybrid Energy Harvester in Ubiquitous Devices: A ReviewMichelle Lim Sern Mi, Sawal Hamid Muhammad Ali, Md Shabiul IslamThis research work presents a novel architecture of an Ultra-Low-Power (ULP) based Hybrid Energy Harvester (HEH) consisting of multiple input sources such as kinetic, thermal and solar energy, harvested from passive human power. Having multiple ambient sources mitigates limitations caused by single sources especially for bodily-worn applications; however, this results in impedance mismatch among the different integrated sources. To overcome … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of Interleaved Boost Converter with LC Coupled Enhanced Soft SwitchingR. Vijayabhasker, S. Palaniswami, V. Venkatesa Kumar, M. Newlin Raj KumarAn enhanced soft switching technique for an interleaved boost converter with Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS) during OFF and ON conditions of the main switches, that can drive large loads operated in duty cycle greater than 0.5 is proposed in this study. In this topology, auxiliary circuit is composed of resonant tank which is used to … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 10 Apr 2013 · 6,091 accessesView PDFCite
