This book was released on 2012 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microelectromechanical system (MEMS) vibration based energy harvesters have become significantly popular due to the growing demand of wireless sensor networks which need miniature, portable, long lasting and easily recharged sources of power. Usage of hazardous batteries is an unacceptable solution to power up the densely populated nodes due to their bulky sizes and high battery replacement cost. Piezoelectric devices are the perfect candidate for implementation in micro generators as they are easily fabricated, are silicon compatible and demonstrate high efficiencies for mechanical to electrical energy conversion. This work presents the design, simulation and fabrication of MEMS piezoelectric energy harvesters. The energy harvester was formed using Aluminium doped Zinc Oxide (AZO) cantilever beams with either Aluminium or Steel contacts. FEM simulation analysis was done to obtain the resonance frequency that provides maximum displacement of vibration and maximum output power. AZO/Steel and Al/AZO/Al/Si structures were successfully simulated, fabricated and experimentally measured. The fabricated AZO/Steel beam produced 4.2 Vs/m2 at the resonant frequency of 137.157 Hz. The Al/AZO/Al/Si beam operates at higher frequencies where it produced 3.2 V AC output voltages at resonance frequencies of 8.026 MHz. The proposed designs can be positioned on a gas turbine in power plant where at a critical vibration pattern it will generate power to activate a wireless sensor to caution for maintenance.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design and analysis of an experimental test bench for the characterization of piezoelectric microelectromechanical system (MEMS) energy harvester being developed by the Micro & Nano Systems Laboratory research group at MIT. Piezoelectric MEMS energy harvesters are micro-devices that are able to harvest energy from their ambient vibrations using piezoelectric material property, and many different designs are being researched by the Micro & Nano Systems Laboratory. In order to analyze the different designs, it is crucial to have a flexible test bench, and the test bench created in this thesis allows data to be gathered easily from different energy harvesters. After the test bench is designed and created, it is used to excite a linear cantilever beam energy harvester system at different frequencies and values for open circuit voltage, resonance frequency, and maximum power are calculated from the collected experimental data. In addition, theory behind linear and nonlinear energy harvester systems is investigated and important definitions, characteristics, and equations are summarized in this thesis.

Download or read book The Householder written by Ritu Sharma and published by Hay House, Inc. This book was released on 2018-07-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The roles of men and women in the ancient society were well defined. And even though the institution of marriage has remained the same since aeons, a woman’s purpose and status has drastically changed over the years. Women, since the beginning of time, were always taught that their purpose was to serve men. But now, the idea that women are created for themselves and for their own happiness is beginning to conquer the world. Women, today, are educated, independent, and not at all at the mercy of men. From living their lives as an oppressed gender, women now have an equal role in society. But despite her liberation, women continue to be enchained by the conditionings of the patriarchal mindset. The Householder explores the psychology which is responsible for the biases and prejudices that surround a woman’s identity and sexuality and takes us through her journey of survival in a unanimously skewed world.
Book Synopsis Towards and Embeddable Structural Health Monitoring Sensor by : Anna Marie Mracek
Download or read book Towards and Embeddable Structural Health Monitoring Sensor written by Anna Marie Mracek and published by . This book was released on 2006 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) Untapered bimorph {3-1} Mode and unimorph {3-3} Mode MEMS devices with large proof masses, as well as tapered unimorph devices (both with and without proof masses) are studied and a 2- or 3-parameter geometric optimization is performed. Optimization objectives include power output, operating power density, static power density, and specific power with very different optimum device configurations favored for the different objectives. A {3-3} Mode MEMS unimorph device optimized for static power density is conservatively predicted to generate 1.9 mW/cm3 of electrical power. This optimization is presented graphically and the predicted performance of the optimum {3-3} Mode unimorph devices with proof masses is detailed. It is found that the optima occur within the micro-scale design space studied, suggesting that MEMS devices are the best choice for distributed aircraft vibrational energy harvesting. The optimization results presented are for one potential SHM vibration environment using cantilevered beam harvesters, however, the technique presented can be extended to other environments and other harvester geometries.

Book Synopsis Teach a Woman to Fish by : Ritu Sharma
Download or read book Teach a Woman to Fish written by Ritu Sharma and published by St. Martin's Press. This book was released on 2014-06-10 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the old axiom goes: "Give a man a fish and he eats for a day. Teach a man to fish and he eats for a lifetime." But teach a woman to fish, and everyone eats for a lifetime. In this firsthand account, Ritu Sharma shares how women can, and are, overcoming the forces that keep them in poverty. She chronicles her travels through four countries—Sri Lanka, Burkina Faso, Honduras, and Nicaragua—and the intimate interactions she had with the women living there. Sharma's story not only details her experiences, but also looks at the broader systems that prevent women from leaving poverty behind. From lack of property rights and government corruption to the scarcity of basic infrastructure like roads, these women are restricted by the external limitations placed upon them. Sharma draws from her experiences to frame a larger exploration of how Americans can be instrumental in helping women break free of restrictive systems and begin to facilitate women's upward mobility. Written in her engaging personal voice, Teach a Woman to Fish provides an insider's look at women in poverty, how Washington works, and how change really happens—from the United States to the rest of the world.
