Abstract:
Portable electronic devices are very popular nowadays. Almost all portable devices are battery powered, meaning that eventually, they all must be recharged–using the wired chargers currently being used. As the usage of these portable electronic devices is increasing, the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while, especially when there is no power outlet around. Now instead of plugging in a cell phone, Personal Digital Assistant (PDA), digital camera, voice recorder, mp3 player or laptop to recharge it, it could receive its power wirelessly. The technology for Wireless Power Transmission or Wireless Power Transfer or Transmission (WPT) is in the forefront of electronic development. WPT systems are designed to transmit power without using wires more efficient than transmitting it while using wires. There could be large number of applications for wireless power systems. Hence, in this work, a wireless battery charger has been proposed for mobile phone charging which is expected to eliminate all the hassles with today’s battery technology. The advantage of this device is that it can wirelessly charge up the batteries which can save time and money in a long run for the general public.

Abstract:
Because of recent advances in wireless power transfer technologies, several key topics of wireless sensor networks (WSNs) need to be revisited. Traditional data collection methods for WSNs typically consider the balance of power consumption among sensors as a critical design criterion for avoiding uneven power depletion in the networks. I propose a solution for the uneven power consumption problem of data collection over WSNs. I designed a node-Gosper island-based scalable hierarchical cluster transmission method in conjunction with a wireless recharge plan for data collection over rechargeable WSNs. For the recharge plan, I used a mobile wireless charger to visit and recharge the batteries of sensors located on different levels of node-Gosper curves with various frequencies. The duration of each recharging process for each layer of sensors was calculated to verify the feasibility of the proposed recharge plan. The simulation results indicate that my proposed data collection method outperforms several well-known data collection methods in terms of energy consumption.

Abstract:
A wireless charging pad for drones based on resonant magnetic technology to recharge the internal battery is presented. The goal of the study was to design a robust, reliable and efficient charging station where a drone can land to automatically recharge its battery. The components of the wireless power transfer (WPT) system on board the drone must be compact and light in order not to alter the payload of the drone. In this study, the non-planar receiving coil of the WPT system is integrated into the drone’s landing gear while the transmitting pad is designed to be efficient for any landing point and orientation of the drone in the charging pad area. To meet these requirements, power transmission is accomplished by an array of planar coils integrated into the ground base station. The configuration of the WPT coil system, including a three-dimensional receiving coil and a multicoil transmitter, is deeply analyzed to evaluate the performance of the WPT, considering potential lateral misalignment and rotation of the receiving coil due to imprecise drone landing. According to the proposed configuration, the battery of a light drone (2 kg in weight and 0.5 kg in payload) is recharged in less than an hour, with an efficiency always greater than 75%.

Abstract:
Because wireless sensor networks (WSNs) have low-constrained batteries, optimizing the network lifetime is a primary challenge. Rechargeable batteries are a solution to prolong the lifetime of a sensor node instead of restricting their functionalities to save energy. Wireless energy transmitters have the added benefit of providing a charger for the batteries of the sensor nodes in the WSN. However, scheduling one or more charging vehicles efficiently to recharge multiple sensor nodes is challenging. In this context, this paper provides a solution to recharge the sensor nodes using charging vehicle scheduling in WSNs through a mixed linear programming approach. Initially, we identify a heuristic value of each sensor node based on their residual energy, distance from a charging vehicle, available data packets, and other metrics. Further, a set of nodes is recharged by identifying the best charging vehicle to prolong their lifetimes, as well as the lifetime of the network as a whole. We simulated the proposed approach using a Python simulator, tested using different performance metrics, and compared using the recently published works. We notice the superior performance of the proposed work under various metrics in time and query-driven WSNs.

<span lang="EN-US">The wireless rechargeable sensor network is attractive crucial and important in recent years for the advancement of wireless energy communication skill. The previous explore shown that not all of sensors can be recharged due to the limitation of power capacity to mobile chargers can carry. If a sensor playing a critical role in a sensing task cannot function as usual due to the exhausted energy, then the sensing task will be interrupted. Therefore, this paper proposes a novel recharging mechanism taking the priorities of sensors into consideration such that mobile chargers can recharge the sensor with a higher priority and the network lifetime can be efficiently sustained. The priority of each sensor depends on its contribution to the sensing task, including the coverage and connectivity capabilities. Based on the priority, the sensor with a higher priority will be properly recharged to extend the network lifetime. Simulation results show that the proposed mechanism performs better against the related work in network lifetime.</span>

Abstract:
In the context of Internet of Things (IoT) for Smart City (SC) applications, Mobile Data Collectors (MDCs) can be opportunistically exploited as wireless energy transmitters to recharge the energy-constrained IoT sensor-nodes placed within their charging vicinity or coverage area. The use of MDCs has been well studied and presents several advantages compared to the traditional methods that employ static sinks. However, data collection and transmission from the hundreds of thousands of sensors sparsely distributed across virtually every smart city has raised some new challenges. One of these concerns lies in how these sensors are being powered as majority of the IoT sensors are extremely energy-constrained owing to their smallness and mode of deployments. It is also evident that sensor-nodes closer to the sinks dissipate their energy faster than their counterparts. Moreover, battery recharging or replacement is impractical and incurs very large operational costs. Recent breakthrough in wireless power transfer (WPT) technologies allows the transfer of energy to the energy-hungry IoT sensor-nodes wirelessly. WPT finds applications in medical implants, electric vehicles, wireless sensor networks (WSNs), unmanned aerial vehicles (UAVs), mobile phones, and so on. The present study highlights the use of mobile collectors (data mules) as wireless power transmitters for opportunistic IoT-SC operations. Specifically, mobile vehicles used for data collection are further exploited as wireless power transmitters (wireless battery chargers) to wirelessly recharge the energy-constrained IoT nodes placed within their coverage vicinity. This paper first gives a comprehensive survey of the different aspects of wireless energy transmission technologies—architecture, energy sources, IoT energy harvesting modes, WPT techniques and applications that can be exploited for SC scenarios. A comparative analysis of the WPT technologies is also highlighted to determine the most energy-efficient technique for IoT scenarios. We then propose a WPT scheme that exploits vehicular networks for opportunistic IoT-SC operations. Experiments are conducted using simulations to evaluate the performance of the proposed model and to investigate WPT efficiency of a power-hungry opportunistic IoT network for different trade-off factors.

Abstract:
This paper addresses a multiobjective Unmanned Aerial Vehicle (UAV) and Unmanned Ground Vehicle (UGVs) collaboration scheduling problem in which UAVs must be recharged periodically during a persistent task, such as wireless communication and making aerial panoramic VR video by UAV. The proposal is to introduce a UGV/UAV cooperative system in which UAVs should be recharged by UGVs periodically, and also, the UGVs have to visit their task points expect for the recharge points. The objective of the problem is to schedule and plan paths with the tradeoff of path length and makespan for UAVs and UGVs. The mathematical model which can be considered a combinatorial multiobjective optimization problem is presented firstly, and the solution of the problem is composed of presubsolution and postsubsolution. The multiobjective adaptive large neighborhood is hybrid with the Pareto local search (MOALP) to resolve the problem. The experimental result shows that the proposed algorithm outperforms the compared algorithms on the rendezvous planning problem for UAVs and UGVs working collaboratively in intelligent tasks.

Abstract:
In modern implantable medical devices (IMDs), wireless power transmission (WPT) between inside and outside of the animal body is essential to power the IMD. Unlike conventional WPT, which transmits the wireless power only between fixed Tx and Rx coils, the wirelessly-powered cage system can wirelessly power the IMD implanted in a small animal subject while the animal freely moves inside the cage during the experiment. A few wirelessly-powered cage systems have been developed to either directly power the IMD or recharge batteries during the experiment. Since these systems adapted different power carrier frequencies, coil configurations, subject tracking techniques, and wireless powered area, it is important for designers to select suitable wirelessly-powered cage designs, considering the practical limitations in wirelessly powering the IMD, such as power transfer efficiency (PTE), power delivered to load (PDL), closed-loop power control (CLPC), scalability, spatial/angular misalignment, near-field data telemetry, and safety issues against various perturbations during the longitudinal animal experiment. In this article, we review the trend of state-of-the-art wirelessly-powered cage designs and practical considerations of relevant technologies for various IMD applications.

Abstract:
Les travaux de recherche de cette thèse sont menés dans le cadre d’une collaboration entre le laboratoire GeePs et l’institut VEDECOM.Le coût, le volume et le poids des batteries électrochimiques représentent encore un frein important au déploiement des véhicules électriques (VE). Une des solutions envisagées pour prolonger l’autonomie des VE sans augmenter démesurément la capacité des batteries, consiste à utiliser des systèmes de transfert d’énergie électrique sans contact pour les alimenter pendant leurs déplacements. Cette thèse porte sur une de ces techniques et plus particulièrement sur le transfert d’énergie inductif résonant. Les problématiques liées à ce mode de transfert d’énergie sont principalement liées au rendement énergétique, à l’encombrement contraint du fait de la nécessité d’intégration dans le véhicule et dans la route ainsi qu'au respect des normes d’émissions électromagnétiques.L’efficacité énergétique du transfert d’énergie est au premier ordre lié au couplage des deux bobines (coupleur magnétique). Une comparaison des coefficients de couplage pour différentes géométries de coupleurs et différentes configurations de désalignement fait l’objet d’une première partie du travail réalisé. Dans la seconde partie une approche à base de sources équivalentes est proposée pour le prédimensionnement analytique d’une plaque de blindage destinée à limiter le rayonnement du coupleur dans le véhicule et en dehors de celui-ci. Dans le dernier axe de la thèse, l’étude est dédiée aux techniques de détection de la présence du véhicule et au séquencement de l’alimentation des bobines au sol. Une solution originale, permettant de répondre à cette problématique est proposée. Le bilan des travaux ainsi que les perspectives envisagées, viennent clôturer ce manuscrit
This thesis is carried out in collaboration between the GeePs laboratory and the VEDECOM institute. The cost, volume and weight of electrochemical batteries still represent a major obstacle to the deployment of electric vehicles (EVs). One of the solutions being considered to extend the range of EVs without excessively increasing the capacity of the batteries, is to use contactless electrical energy transfer systems to power them while they are on the move. This thesis focuses on one of these techniques which is the resonant inductive energy transfer. The problems associated with this mode of energy transfer are mainly related to energy efficiency, the size constrained due to the need for integration into the vehicle and the road as well as compliance with electromagnetic emissionstandards. The efficiency is directly linked to the coupling of the two coils (magnetic coupler). A comparison of the coupling coefficients for different coupler geometries and different misalignment configurations is the subject of the first part of this work. In the second part, an approach based on equivalent sources is suggested for the analytical pre-dimensioning of shielding plate intended to limit the magnetic emissions in and outside the vehicle. In the last axis of the thesis, the study is dedicated to techniques for detecting the presence of the vehicle and the sequencing of the different ground coils.

Abstract:
Dans cette thèse, nous abordons la question des champs magnétiques générés par les systèmes de transfert d’énergie sans contact pour les véhicules en mouvement. En effet, ces systèmes utilisent de fortes puissances afin de transférer le plus d’énergie possible en un laps de temps très court, par conséquent, les champs magnétiques mis en jeu sont très intenses et peuvent être nocifs pour la santé humaine. L’objectif des travaux présentés dans ce document est de développer une plateforme de simulation, permettant d’obtenir la répartition des champs magnétiques autour du coupleur pour des systèmes génériques (indépendant de la géométrie ou de la fréquence), afin de mettre en place les périmètres de sécurité visant à garantir la sécurité physique des usagers. Les chapitres de ce manuscrit illustrent, étape par étape, la modélisation, la cosimulation et la validation expérimentale d’un système de charge sans contact simplifié en mouvement. En effet, d’une part une méthodologie de modélisation du coupleur conjuguée à la simulation globale du système de charge sans contact est proposée, et d’autre part, un modèle analytique est développé permettant de calculer les courants induits dans le secondaire d’une configuration simpliste du coupleur, ce modèle se distingue par un temps de résolution très court et des résultats très précis. Afin de valider l’approche de modélisation développée, un banc de test expérimental est réalisé. Les grandeurs électriques (courants, tensions) et magnétiques (inductances, induction magnétique) calculées numériquement sont confrontées aux mesures réalisées sur ce banc, dans le but d’attester de la précision des modèles de simulation et du modèle analytique proposés
This thesis deals with the magnetic fields generated in the vicinity of a dynamic wireless power transfer system for electric vehicles. The objective of this work is to develop a novel methodology dedicated to these systems, fully independent of the characteristics of the system (i.e. geometry and frequency). The magnetic fields generated by such systems can be harmful to human health, since they are induced by high intensity currents in order to transfer high power in short ranges, thus the assessment of the magnetic fields in vicinity of the system is critical for this technology. The chapters of this thesis describe step by step, the modeling, the co-simulation and the experimental validation of a simplified dynamic wireless power transfer system. Indeed, a modeling methodology of the coupler considering the simulation of the whole system is suggested. Furthermore, an analytical model was developed especially for these systems, in order to get the induced current in a short time for any generic system. For the purpose of approving the modeling approach, an experimental bench consisting of a real scale dynamic wireless power transfer system was designed in order to compare the electric (current, voltage) and the magnetic quantities (inductance, magnetic induction) obtained from the simulation and from the experimental data

Abstract:
abstract: A new loop configuration capable of reducing power radiation magnitudes lower than conventional loops has been developed. This configuration is demonstrated for the case of two coaxial loops of 0.1 meter radius coupled via the magnetic reactive field. Utilizing electromagnetism theory, techniques from antenna design and a new near field design initiative, the ability to design a magnetic field has been investigated by using a full wave simulation tool. The method for realization is initiated from first order physics model, ADS and onto a full wave situation tool for the case of a non-radiating helical loop. The exploration into the design of a magnetic near field while mitigating radiation power is demonstrated using an real number of twists to form a helical wire loop while biasing the integer twisted loop in a non-conventional moebius termination. The helix loop setup as a moebius loop convention can also be expressed as a shorted antenna scheme. The 0.1 meter radius helix antenna is biased with a 1MHz frequency that categorized the antenna loop as electrically small. It is then demonstrated that helical configuration reduces the electric field and mitigates power radiation into the far field. In order to compare the radiated power reduction performance of the helical loop a shielded loop is used as a baseline for comparison. The shielded loop system of the same geometric size and frequency is shown to have power radiation expressed as -46.1 dBm. The power radiated mitigation method of the helix loop reduces the power radiated from the two loop system down to -98.72 dBm.

Background: For the study of long-time rhythms, such as circadian rhythms, seasonal changes and circannual cycles, and for the investigation of subtle physiological variations, such as sleep-wake transitions, autonomic functions, blood pressure, and activities, a technique with continuous recordings of physiological signals for more than 24 hours is required. However, the current equipment, either cable recording or battery operated wireless recording, cannot meet the requirement. Aim: To integrate wireless recharge technique with multi-physiological signals wireless recording system, for the continuous recording of electroencephalogram, electromyogram, electrocardiogram and 3-axis acceleration signals, on which to establish the index for sleep wake discrimination. Results: The system is composed of four circuit units, including microcontroller, RF transceiver, analog amplifier, and RF recharged circuit. The RF recharged circuit works at resonance frequency to get power. The wireless sensor (size: 4*2*1 cm, weight: 8.3 g) was intra-abdominally implanted in Wistar-Kyoto rats for the study of short-term and long-term relationships of sleep-wake cycles and activities. The EEG, EMG, ECG, and 3-axis acceleration signals had been recorded continuously for more than 15 days without interruption. We found characteristic distributions of 3-axis acceleration signals across sleep-wake cycle, and the indicator of activity can be used for discriminating difference between Wistar-Kyoto rats (WKY) and Spontaneously hypertensive rats (SHR) activity. Conclusion: Our system is suitable for ultra-long term recording of physiological signals and behaviors, with short-term, long-term or even lifelong rhythm. Besides, we establish an index using activities to discriminate between sleep and wake states with a correct rate over 90 %.

Abstract:
This chapter deals with the problem of energy storage inside an electric vehicle. The main source of energy is based on a wireless system. This recharge tool regroups inside several components as the storage system, which consists of an ensemble of batteries and serving as the main power source, a special electronic converter that is based on the buck-boost principle and a coil receiver placed undo the vehicle. From the other side, one or more than coil transmitters are placed on the road, where the vehicle is. Modeling all of these components and expressing their mathematical models seems interesting for defining the possible control method that can guarantee a high autonomy when the vehicle is moving. So, taking into account if the care is driving or stopped, this recharge system is studied for verifying the effectiveness of this recharge system and showing the relationship between the vehicle situation and the quantity of received power. Using the platform Matlab/Simulink the results were shown and discussed.

Abstract:
Wireless sensor nodes generally operate using energy from source line batteries, which need to be replaced or recharge from time to time. The connection of electromagnetic energy to DC energy, which is called radiofrequency (RF) energy harvesting, is one of the best techniques to act as an energy source for this equipment. An ambient amount of RF energy is present in our environment radiated from numerous sources so that it can act as a much predictable source of energy as compared to other techniques of energy harvesting. This system eliminates the periodic replacement of energy batteries for these sensor nodes. Despite the enormous RF energy present in the environment, the power per unit area is quite low. Hence, the major barrier is to increase the output of the rectifier circuit, even though the power density is low.

Abstract:
This chapter presents state-of-the-art and major developments in wireless power transfer using solar energy. The brief state-of-the-art is presented for solar photovoltaic technologies which can be combined with wireless power transfer (WPT) to interact with the ambient solar energy. The main purpose of the solar photovoltaic system is to distribute the collected electrical energy in various small-scale power applications wirelessly. These recent developments give technology based on how to transmit electrical power without any wires, with a small-scale by using solar energy. The power can also be transferred wirelessly through an inductive coupling as an antenna. With this wireless electricity we can charge and make wireless electricity as an input source to electronic equipment such as cellphone, MP3 Player etc. In harvesting energy, technologies of ambient solar radiation like solar photovoltaic, kinetic, thermal or electro-magnetic (EM) energy can be used to recharge the batteries. Radio frequency (RF) harvesting technologies are also popular as they are enormously available in the atmosphere. The energy converted to useful DC energy which can be used to charge electrical devices which need low power consumption. The chapter has also presented a parallel plate photovoltaic amplifier connected to a potentiometer as a Resistance-Capacitance (RC) circuit power amplifier. The effect of inductance and resulting power transfer has been theoretically determined in the RC amplifier circuit. The electrical and thermal properties and measurements from a parallel plate photovoltaic amplifier were collected to analyze the unbalanced power transfer and inductance in a nonlinear RC circuit amplifier using equivalent transfer functions. The concept of Wireless Information and Power Transfer using Electromagnetic and Radio Waves of Solar Energy Spectrum is also briefly outlined.

Abstract:
Energy efficiency is a major issue of concern in wireless ad hoc networks as mobile nodes rely on batteries, which are limited sources of energy, and, in many environments, it is quite a cumbersome task to replace or recharge them. Despite the progress made in battery technology, the lifetime of battery powered devices continues to be a key challenge, requiring additional research on efficient design of platforms, protocols, and systems. Many tangible efforts are made by many researchers to reduce the power consumption at protocol level by designing an energy efficient protocol to prolong the lifetime of the networks. The main focus of this chapter is to present a comprehensive analysis of energy efficient techniques in wireless ad hoc networks, integrating various issues and challenges to provide a big picture in this area. This chapter addresses energy management techniques in wireless ad hoc networks, especially in decentralized ad hoc environments.

Abstract:
Sensor networks are composed of miniaturized wireless sensor nodes with limited capacity and energy source. Generally, these sensor networks are used, in many applications, to monitor inaccessible environments (battlefields, volcano monitoring, animal tracking…), hence the impossibility to replace or to recharge the batteries. As sensors may be deployed in a large area, radio transceivers are the most energy consuming of sensor nodes, which means that their usage needs to be very efficient in order to maximize node life, which leads us to maximize the network's life. In wireless sensor networks and in order to transmit its data, a node can route its messages towards destination, generally the base station, either by using small or large hops, so optimizing the hop length can extend significantly the lifetime of the network. This chapter provides a simple way to verify, which makes the energy consumption minimal by choosing proper hop length.

Abstract:
This chapter provides a detailed study on the harvest of the energy contained in raindrops by means of piezoelectric transducers. The energy harvester has the role of an electric source, able to recharge storage devices of small electronic components, such wireless sensors, by using the vibrational energy released by the drops hitting the transducer, reducing in such a way the chemical waste of conventional batteries. In technical literature, diverse studies agree on the level of suitable generated voltage on the electrodes of a piezoelectric transducer subjected to rainfall, but a complete characterization on the supplied power is still missing. This work, also to limit optimistic forecasts, takes into account the behavior of the transducers in different scenarios: subjected to real and artificial rainfall, standalone or in parallel configuration, in conventional geometries, due to the commercial format or in customized shape, free to move or with an imposed optimal deflection.

Abstract:
Wireless Body Sensor Network is a collection of physiological sensors connected to small embedded machines and transceivers to form a monitoring scheme for patients and elderly people. Intrusion and foolproof routing has become mandatory as the Wireless Body Sensor Network has extended its working range. Trust in Wireless Body Sensor Network is greatly determined by the Encryption key size and Energy of the Node. The Sensor Nodes in Wireless Body Sensor Network is powered by small battery banks which are to be removed and recharged often in some cases. Attack to the implanted node in Wireless Body Sensor Network could harm the patient. Finite State Machine helps in realizing the Trust architecture of the Wireless Body Sensor Network. Markov model helps in predicting the state transition from one state to other. This chapter proposes a Trustworthy architecture for creating a trusted and confidential communication for Wireless Body Sensor Network.
