Nanotechnology is already inherent in communication modules through the ubiquitous use of low cost, highly functional silicon integrated circuits. Motion processing units, portable biomedical sensors, and imaging sensors are discussed along with relevant nanotechnologies, both current and imminent. Nanotechnology-enhanced glucose sensors are expected in commercial glucose monitoring systems in the next few years. Nevertheless, advances in nanotechnology could soon play a significant role in the evolution of optical sensors for consumer electronics. Nanotechnology is expected to play a significant role in the technology evolution of organic light-emitting diode (OLED) devices. Nanotechnologies are of critical importance to the progress of liquid crystal displays (LCDs), electrophoretic, and electrochromic displays, all of whose operating principles fundamentally rely on nanoscaled structures. Nanotechnology is essential to the continuing advances in integrated electronics: increasing computational power, reducing device scale, and limiting energy consumption.
Kiziroglou M, Becker T, Wright SW, et al., 2017, Three-Dimensional Printed Insulation For Dynamic Thermoelectric Harvesters With Encapsulated Phase Change Materials, IEEE Sensors Letters, Vol: 1, ISSN: 2475-1472
Energy harvesting devices have demonstrated their ability to provide power autonomy to wireless sensor networks. However, the adoption of such powering solutions by the industry is challenging due to their reliance on very specific environmental conditions such as vibration at a specific frequency, direct sunlight, or a local temperature difference. Dynamic thermoelectric harvesting has been shown to expand the applicability of thermoelectric generators by creating a local spatial temperature gradient from a temporal temperature fluctuation. Here, a simple method for prototyping or short-run production of such devices is introduced. It is based on the design and 3-D printing of an insulating container, insertion of a phase change material in encapsulated form, and use of commercial thermoelectric generators. The simplicity of this dry assembly method is demonstrated. Two prototype devices with double-wall insulation structures are fabricated, using a stainless-steel and a plastic phase change material encapsulation and a commercial TEG. Performance tests under a temperature cycle between ±25 °C show energy output of 43.6 and 32.1 J from total device masses of 69 and 50 g, respectively. Tests under multiple temperature cycles demonstrate the reliability and performance repeatability of such devices. The proposed method addresses the complication of requiring a wet stage during the final assembly of dynamic thermoelectric harvesters. It allows design and customization to particular size, energy, and insulation geometry requirements. This is important because it makes dynamic harvesting prototyping widely available and easy to reproduce, test, and integrate into systems with various energy requirements and size restrictions.
Kiziroglou ME, Becker T, Yeatman EM, et al., 2017, Comparison of methods for static charge energy harvesting on aircraft, ISSN: 0277-786X
© 2017 SPIE. In this paper, the possibility of using the static charge that accumulates on aircraft during flight as a source to power monitoring sensors is examined. The assessed methods include using a pair of materials with different air-flow charging rates, contact discharging of the fuselage to neutral metallic bodies, charge motion induction by the fuselage field and inductive harvesting of fuselage-to-air corona discharges at static discharge wicks. The installation and potential advantages of each method are discussed. The feasibility of directly charging a storage capacitor from accumulated static charge is studied experimentally, demonstrating a voltage of 25V on a 25nF capacitor.

There are many potential applications in the utilities, critical infrastructure monitoring and control and environmental monitoring. This article charts the device-level technologies used in the creation the IoT, including hardware, software and communications. IoT's emergence coincided with the development of radio frequency identification (RFID) technology offering advantages such as the communicable range, ability to write data to a tag, and the possibility of reading multiple tags more efficiently with a single reader. RFID is now just one of many component IoT technologies. We have arrived at a situation where it is practically trivial to integrate computation and communication into any manufactured thing, and it is equally feasible to connect and technologically perceive natural things using communicable sensors. Furthermore, it is possible to react to, and control the environment using embedded computing devices coupled with actuators. Thorough comprehension of functional and non-functional requirements is necessary to develop an effective, efficient design specification for an IoT device. But given the large design space and complexity, there are numerous barriers to entry. As a result, many types of device have been adopted as practical de facto hardware development platforms across research communities, anc hacker and maker communities. In each case, intermediary 'operating systems', designed to simplify their programming by masking hardware complexity, are typically used. Their technical specifications are often not fully disclosed, but they do rely on well- defined standards to ensure the necessary interoperability. The majority of devices are characterised as single board computers. The final design for a market-ready product will likely be as efficient and cost-effective as possible in terms of design, but include sufficient redundancy to support software updates and potential shifts in standards. Since the early 2000s, the wireless sensor network comm
Briand D, Yeatman E, Roundy S, 2015, Introduction to Micro Energy Harvesting, ISBN: 9783527672943
© 2015 Wiley-VCH Verlag GmbH & Co. KGaA. All rights reserved. This introductory chapter provides an overview of the book Micro Energy Harvesting and its chapters. This book is intended to cover the engineering fundamentals and current state of the art associated with energy harvesting at the small scale, or micro energy harvesting. The term "energy harvesting" usually refers to devices or systems that capture (or harvest) ambient energy in the environment, and convert it into a useful form, which is usually electricity. Of the main types of energy harvesting for small-scale applications, solar (or photovoltaic (PV)) cells are the most mature and long established, with devices such as PV-powered pocket calculators having been available for over 30 years. The book covers fundamentals and devices for harvesting energy from vibrations, fluid flow, acoustics, heat, light, RF radiation, and chemicals. An emphasis is especially given on the topics of kinetic and thermal energy harvesting for which microscale technologies have been readily developed.
