Power Consumption

The vast reduction in size and power consumption of CMOScircuitry has led to a large research effort based around the visionof ubiquitous networks of wireless communication nodes. The wirelessdevices are usually designed to run on batteries. However, as thenetworks increase in number and the devices decrease in size, thereplacement of depleted batteries is not practical. Furthermore, abattery that is large enough to last the lifetime of the device woulddominate the overall system size, and thus is not very attractive.There is clearly a need to explore alternative methods of poweringthese small communication nodes. This book, therefore, focuses onpotential "ambient" sources of power that can be scavenged orharvested and subsequently used to run low power electronics andwireless transceivers.A wide range of potential power sources are briefly explored. Based ona comparison of these many potential sources, commonly occurringvibrations was chosen as an attractive, and little explored, powersource. Models for different types of power converters using bothelectrostatic and piezoelectric conversion mechanisms have beendeveloped. The models have been validated by testing prototypes drivenat vibrations similar to those found in many industrial and commercialbuilding environments. Finally, integration of a piezoelectricgenerator, power circuit, and custom design radio transceiver isdemonstrated.Power sources are becoming a bottleneck to the widespread deploymentof wireless sensor networks. This work reviews many potentialalternative sources of ambient power that can be scavenged. Vibrationto electricity converters are explored in great detail, and based onstudies and experiments, are shown to bean attractive power source inmany applications."Energy Scavenging for Wireless Sensor Networks with Special Focuson" "Vibrations" will be of interest to researchers andprofessionals in the areas of wireless electronics, smart structuresand MEMS as well as power electronics.

Comforting terms such as "sustainable development" and "green production" frame environmental debate by stressing technology (not green enough), economic growth (not enough in the right places), and population (too large). Concern about consumption emerges, if at all, in benign ways--as calls for green purchasing or more recycling, or for small changes in production processes. Many academics, policymakers, and journalists, in fact, accept the economists' view of consumption as nothing less than the purpose of the economy. Yet many people have a troubled, intuitive understanding that tinkering at the margins of production and purchasing will not put society on an ecologically and socially sustainable path."Confronting Consumption places consumption at the center of debate by conceptualizing "the consumption problem" and documenting diverse efforts to confront it. In Part 1, the book frames consumption as a problem of political and ecological economy, emphasizing core concepts of individualization and commoditization. Part 2 develops the idea of distancing and examines transnational chains of consumption in the context of economic globalization. Part 3 describes citizen action through local currencies, home power, voluntary simplicity, "ad-busting," and product certification. Together, the chapters propose "cautious consuming" and "better producing" as an activist and policy response to environmental problems. The book concludes that confronting consumption must become a driving focus of contemporary environmental scholarship and activism.

Power consumption - In electrical engineering, power consumption refers to the electrical energy over time that must be supplied to an electrical device to maintain its operation

Power optimization (EDA) - Power optimization refers to the use of electronic design automation tools to optimize (reduce) the power consumption of a digital design, while preserving the functionality.

Power analysis - In cryptography, power analysis is a form of side channel attack in which the attacker studies the power consumption of a cryptographic hardware device (such as a smart card, tamperproof "black box", microchip, etc). It can yield information about what the device is doing, and sometimes even some key material.

Differential power analysis - Differential power analysis (DPA) is a method of attacking a cryptosystem which exploits the varying power consumption of microprocessors while executing cryptographic program code. It is a side-channel attack.
