However, as the number of sensors in a wearable device increases together with continuous monitoring and wireless communications, the battery lifetime and battery duration per charge becomes a major concern. This issue is particularly important for health monitoring of workers operating in difficult environments such as emergency response responders, mining and construction. In this paper, we present a wireless charging system for a health monitoring smart-wear application of workers by considering the power consumption requirements of sensory hardware, communication technology as well as the practical charging scenarios. We also demonstrate a working prototype of a 5-Watt wireless charging device used by our health monitoring wearable. Our paper provides the design, analysis of the requirements and the critical factors of a ‘wireless charging bin’ that we are currently prototyping for our application context.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126772344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compensation topologies play significant role in improving the power transfer performance of a CPT system, so many different topologies have been proposed and investigated. This paper presents a comparative study of six compensation networks, namely single L, double-sided LC, LCL, LCLC, CLLC, and LCLC-LC for CPT systems. Based on the first five topologies that are already utilized in CPT systems, a new LCLC-LC topology is investigated in this research. The advantages and disadvantages of these compensation topologies are summarized by analyzing their equivalent circuit models, power transfer characteristics against the load, coupling, and frequency variations. It has found if the series equivalent resistances are ignored, all these five topologies can be designed to achieve constant voltage or constant current output against load variations under fully tuned conditions. However, their output power changes with coupling variation. The steady state analysis of the impedance transformation and voltage or current source characteristics has shown that the double-sided LC topology can be tuned to achieve a constant output voltage against both coupling and load variations.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121896824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One design objective of transcutaneous energy transfer systems is a robust power supply to the implanted components. A varying coupling factor can significantly affect the transferred power, which potentially leads to the requirement of complex monitoring and control circuits. The proposed design procedure eliminates the variation of the coupling factor of a planar, rotationally symmetrical coil in lateral direction. This is achieved only by adjusting individual winding positions of the primary coil. The winding distribution of the secondary coil is adjusted for its maximum achievable efficiency. The design steps, based on analytical modeling, are described in detail. The results show that the coupling factor of a coil system with radii of 40 mm and 25 mm on primary and secondary side, respectively, can be kept almost constant for a lateral misalignment of over 50% of the secondary coil's radius.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123580396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such devices on a network often have individual batteries for each sensor node. This requires each battery either to be recharged by a nearby energy source (solar or DC source) or be replaced. In many applications it is quite challenging to supply power for a distributed sensor network with nearby energy sources. Here we present a method utilizing Quasi-Wireless Capacitive (QWiC) power transfer to operate a single sensor node over a transmission line with a stray capacitive ground return path. This allows the sensor node to be powered on a single conductive surface without a physical return conductor. We will utilize a Marx inverter to drive the system. The sensor node will be capable of sending sensor data over a wireless far-field RF network. This paper will evaluate the system efficiency and take quantitative measurements of key parameters that define performance. The main aim of this work is to develop a single node that can be flexible enough to allow greater sensor node density in future applications. The resulting system demonstrates the viability of using QWiC power transfer in order to power sensor networks on a single conductive surface.

This paper proposes a real-time algorithm for tracking maximum power when the device is moving in 3D space, which can considerably improve the transfer distance and efficiency could be improved as much as possible by the proposed algorithm under the same hardware condition. By measuring the input power of the wireless power transfer system and monitoring its gradient change, the minimum value of the cost function is dynamically found, and the maximum power transfer is achieved for a moving device without the need to know its position and pose. Plus, communication between the transmitting and receiving coils is avoided. The correctness and convergence of the proposed algorithm are proven by using LaSalle's invariance principle.","PeriodicalId":192132,"journal":{"name":"2020 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129285593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
