Book Description
This book discusses in detail the CMOS implementation of energy harvesting. The authors describe an integrated, indoor light energy harvesting system, based on a controller circuit that dynamically and automatically adjusts its operation to meet the actual light circumstances of the environment where the system is placed. The system is intended to power a sensor node, enabling an autonomous wireless sensor network (WSN). Although designed to cope with indoor light levels, the system is also able to work with higher levels, making it an all-round light energy harvesting system. The discussion includes experimental data obtained from an integrated manufactured prototype, which in conjunction with a photovoltaic (PV) cell, serves as a proof of concept of the desired energy harvesting system.

Book Description
Chip-integrated power management solutions are a must for ultra-low power systems. This enables not only the optimization of innovative sensor applications. It is also essential for integration and miniaturization of energy harvesting supply strategies of portable and autonomous monitoring systems. The book particularly addresses interfaces for energy harvesting, which are the key element to connect micro transducers to energy storage elements. Main features of the book are: - A comprehensive technology and application review, basics on transducer mechanics, fundamental circuit and control design, prototyping and testing, up to sensor system supply and applications. - Novel interfacing concepts - including active rectifiers, MPPT methods for efficient tracking of DC as well as AC sources, and a fully-integrated charge pump for efficient maximum AC power tracking at sub-100μW ultra-low power levels. The chips achieve one of widest presented operational voltage range in standard CMOS technology: 0.44V to over 4.1V. - Two special chapters on analog circuit design – it studies benefits and obstacles on implemented chip prototypes with three goals: ultra- low power, wide supply voltage range, and integration with standard technologies. Alternative design approaches are pursued using bulk-input transistor stages in forward-bias operation for amplifiers, modulators, and references. - Comprehensive Appendix – with additional fundamental analysis, design and scaling guidelines, circuit implementation tables and dimensions, schematics, source code listings, bill of material, etc. The discussed prototypes and given design guidelines are tested with real vibration transducer devices. The intended readership is graduate students in advanced courses, academics and lecturers, R&D engineers.

Book Description
This book covers smart polymer nanocomposites with perspectives for application in energy harvesting, as self-healing materials, or shape memory materials. The book is application-oriented and describes different types of polymer nanocomposites, such as elastomeric composites, thermoplastic composites, or conductive polymer composites. It outlines their potential for applications, which would meet some of the most important challenges nowadays: for harvesting energy, as materials with the capacity to self-heal, or as materials memorizing a given shape.The book brings together these different applications for the first time in one single platform. Chapters are ordered both by the type of composites and by the target applications. Readers will thus find a good overview, facilitating a comparison of the different smart materials and their applications. The book will appeal to scientists in the fields of chemistry, material science and engineering, but also to technologists and physicists, from graduate student level to researcher and professional.

Book Description
The Internet of Everything (IoE) ecosystem of sensor nodes, hubs, and cloud services has grown at a rapid pace, with currently three interconnected devices for every human on earth. Powering these sensor nodes using batteries is not scalable and poses major limitations in terms of their size, cost, and accessibility. Thus, energy harvesting (EH) has been widely considered as a viable alternative for several applications. However, harvesters add their own size and cost to the sensors. To alleviate this shortcoming, the sensor is time-multiplexed to operate as an energy harvester. Specifically, this work focuses on energy harvesting using a CMOS image sensor (CIS) pixels. Many applications like tracking warehouse inventory, detecting structural faults, or detecting movements through a door require image capture at a very low frame rate. A dual-mode image sensor is well suited for such applications. The objective of this work is to demonstrate a self-powered energy harvester using CIS pixels that support the dual-mode operation. Traditional EH image sensors have used increased pixel sizes to incorporate a multiplexer in each pixel. This leads to reduced fill factor and limits its use to certain applications. Under office lighting conditions, the incident power is limited and designing an energy-autonomous system with high efficiency is challenging. The low voltage output from the pixels needs stepping up to generate the power supply rails for the imager readout circuitry. Generating two simultaneous outputs in a fully integrated solution (without using any external inductors) was the primary goal for this work. Further, the harvester needs to operate over a wide range of light intensity and loads as demanded by the application. Another challenge that must be addressed for an EH system is to enable startup without using external batteries or external components that might increase the size and weight of the solution. In this thesis, we employ conventional 4-T CIS pixels that share the mode multiplexers outside the array. In this fashion, we can harvest energy irrespective of the pixel pitch. We achieve the highest fill factor of 60.4% at a pitch of 5 μm with our EH pixels. Fully integrated switched capacitor (SC) DC/DC converters boost the pixel output to the required supply rails. An analytical framework to evaluate the effect of various parasitic capacitances and the load impedance was developed to select the topology with minimum loss. Using this approach, our chip, implemented in a 130 nm CMOS process, achieves a peak power efficiency of 52.4% at an output power of 266 nW. Our self-powered energy harvester can cold start at low light of 25 lux (comparable to a dimly lit room) and tracks light intensity variations to deliver maximum power to the output.
