In deep-submicron processes a significant portion of the power budget is lost in standby power due to increasing leakage effects. For systems that have long idle times punctuated by bursts of activity, such as PDAs, cell-phones, and wireless sensor networks nodes, this standby power consumption reduces the effectiveness of duty-cycling. This work surveys a number of subthreshold leakage reduction techniques and identifies supply rail gating "MTCMOS" as the most promising. MTCMOS is a dynamic technique that has two distinct modes: an active processing mode and a lower power sleep mode. The smallest area implementations of MTCMOS have the side-effect of losing the state of the system when in sleep mode. This complicates the resumption of the active mode, because traditional designs are intolerent to the loss of state. This work presents a general framework to reduce the state maintenence requirements during sleep mode without losing information required to resume the active mode. The framework is applied to finite state machines and microprocessors, since these are commonly used in system design. Partitioning the system into subsystems with individually controlled supply rails "termed power domains" allows fine-grain control of the power mode for portions of the chip. Each power domain must be dynamically put in the appropriate power mode to ensure correct system operation while minimizing power consumption. This control logic collectively forms the core of a power manager. Most power manager implementation approaches are largely ad-hoc and custom designed for each application. This work presents a structured methodology and architecture for the implementation and control of power domains to form a power managed system. Approaches to the partitioning and implementation of individual power domains are explored. The functional requirements for the power manager

Wireless sensors and sensor networks (WSNs) are nowadays becoming increasingly important due to their decisive advantages. Different trends towards the Internet of Things (IoT), Industry 4.0 and 5G Networks address massive sensing and admit to have wireless sensors delivering measurement data directly to the Web in a reliable and easy manner. These sensors can only be supported, if sufficient energy efficiency and flexible solutions are developed for energy-aware wireless sensor nodes. In the last years, different possibilities for energy harvesting have been investigated showing a high level of maturity. This book gives therefore an overview on fundamentals and techniques for energy harvesting and energy transfer from different points of view. Different techniques and methods for energy transfer, management and energy saving on network level are reported together with selected interesting applications. The book is interesting for researchers, developers and students in the field of sensors, wireless sensors, WSNs, IoT and manifold application fields using related technologies. The book is organized in four major parts. The first part of the book introduces essential fundamentals and methods, while the second part focusses on vibration converters and hybridization. The third part is dedicated to wireless energy transfer, including both RF and inductive energy transfer. Finally, the fourth part of the book treats energy saving and management strategies.

The field of computational intelligence has grown tremendously over that past five years, thanks to evolving soft computing and artificial intelligent methodologies, tools and techniques for envisaging the essence of intelligence embedded in real life observations. Consequently, scientists have been able to explain and understand real life processes and practices which previously often remain unexplored by virtue of their underlying imprecision, uncertainties and redundancies, and the unavailability of appropriate methods for describing the incompleteness and vagueness of information represented. With the advent of the field of computational intelligence, researchers are now able to explore and unearth the intelligence, otherwise insurmountable, embedded in the systems under consideration. Computational Intelligence is now not limited to only specific computational fields, it has made inroads in signal processing, smart manufacturing, predictive control, robot navigation, smart cities, and sensor design to name a few.
