“…Recently, researchers from the University of Illinois developed a novel battery that can be 90% charged in 2 minutes [80]. Another hot research topic that must be investigated is wireless powering methods such as light, capacitivo or ultra sonic techniques [81] [82]. Researchers from MIT [83] succeeded in wirelessly powering sensor nodes over several meters using magnetic resonance.…”

Rehabilitation supervision has emerged as a new application of wireless sensor networks (WSN), with unique communication, signal processing and hardware design requirements. It is a broad and complex interdisciplinary research area on which more than one hundred papers have been published by several research communities (electronics, bio-mechanical, control and computer science). In this paper, we present WSN for rehabilitation supervision with a focus on key scientific and technical challenges that have been solved as well as interdisciplinary challenges that are still open. We thoroughly review existing projects conducted by several research communities involved in this exciting field. Furthermore, we discuss the open research issues and give directions for future research works. Our aim is to gather information that encourage engineers, clinicians and computer scientists to work together in this field to tackle the arising challenges.

“…The reported experiment demonstrated a wireless illumination of a 60 W light bulb from 2 meters away and achieved a 40% energy transfer efficiency. Zhang et al [7] apply this technique to replenish battery energy in medical sensors and implantable devices in health care industry. Products from Powercast [8] carry out wireless charging by leveraging the electromagnetic radiation technique, with which energy transmitters broadcast the RF energy and receivers capture the energy and convert it to DC.…”

Abstract-The emerging wireless charging technology creates a controllable and perpetual energy source to provide wireless power over distance. Schemes have been proposed to make use of wireless charging to prolong the sensor network lifetime. Unfortunately, existing schemes only passively replenish sensors that are deficient in energy supply, and cannot fully leverage the strengths of this technology. To address the limitation, we propose J-RoC -a practical and efficient Joint Routing and Charging scheme. Through proactively guiding the routing activities in the network and delivering energy to where it is needed, J-RoC not only replenishes energy into the network but also effectively improves the network energy utilization, thus prolonging the network lifetime. To evaluate the performance of the J-RoC scheme, we conduct experiments in a small-scale testbed and simulations in large-scale networks. Evaluation results demonstrate that JRoC significantly elongates the network lifetime compared to existing wireless charging based schemes.

“…The use of a third intermediate resonant coil is reported in [15]. Four coils make a popular wireless power transfer architecture consisting of driver coil, transmitter coil, receiver coil and load coil [16], this architecture is space demanding and also suffers from high sensitivity to the design parameters which lead to more design complexity, such as tuning the distance between both transmitter coils (driver and transmitter coils) or tuning the resonance frequency of the system [17].The available space, the transfer distance rate, the level of power to be transferred and the system efficiency are the main requirements for the design of such systems. This paper aims to provide a design consideration and methodology to achieve optimal design of resonant magnetic coupler for linear and rotating actuator based on the results of parametric analysis and experimental measurements.…”

Abstract. This paper focuses on the design of a wireless power supply system for low power devices (e.g. sensors) located in harsh electromagnetic environment with ferromagnetic and conductive materials. Such particular environment could be found in linear and rotating actuators. The studied power transfer system is based on the resonant magnetic coupling between a fixed transmitter coil and a moving receiver coil. The technique was utilized successfully for rotary machines. The aim of this paper is to extend the technique to linear actuators. A modeling approach based on 2D Axisymmetric Finite Element model and an electrical lumped model based on the two-port network theory is introduced. The study shows the limitation of the technique to transfer the required power in the presence of ferromagnetic and conductive materials. Parametric and circuit analysis were conducted in order to design a resonant magnetic coupler that ensures good power transfer capability and efficiency. A design methodology is proposed based on this study. Measurements on the prototype show efficiency up to 75% at a linear distance of 20 mm.
