We first used a two-stack hybrid metamaterial slab and it shows considerably the enhanced power transfer efficiency compared to one hybrid metamaterial case. We verified the power transfer efficiency with S-parameter measurement. Thus, we finally achieved maximum 25.4% efficiency enhancement when the distance between Tx and Rx coils is 15 cm, and in overall distance variation cases, the proposed two-stack hybrid metamaterial slab make the power transfer efficiency increase.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133733335","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}

The input source voltage and compensation capacitances are selected as design variables to tune up the optimal resonant condition. The power transfer efficiency is set to be maximized as an objective function, and the target rated power for each receiver module is set as the constraint functions. In the proposed method, design variables are iteratively updated through linking the optimization module and the analysis module. After being verified with the “single transmitter-to-a-single-receiver” WPT system, the proposed method is applied to determine the optimal resonant condition for the multi-module WPT systems.

The proposed system uses the wireless power transfer (WPT) technology based on the magnetic resonant coupling. For this kind of application two main aspects must be taken into account. First, the LVAD is implanted in the heart, so the power must be wirelessly transferred at a significant depth inside the human body. Second, the LVAD requires a much higher power than other active implantable medical devices (AIMDs) and for 24 hours per day, 365 days a year. To this aim an adequate design of the electrogeometrical configuration of the WPT coils is proposed. A feasibility study is therefore carried out to define possible solutions for WPT application to an LVAD.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115683890","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}

Since UAVs for industrial purposes are usually large and carry large batteries, high-power charger is preferable for fast charging. Although wireless charging stations for UAVs have recently been reported in the literature, the charging powers in those reports are 150 W or less, to the knowledge of the authors. This paper summarizes the design of a prototype 450-W inductive power transfer system in the 85-kHz band for application to the wireless charging port of a large UAV and reports the measured results. The proposed structure and shape of the wireless charging port for the UAV is described. The measurement of the prototype shows that received dc power is approximately 450 W, indicating the potential for application to the fast wireless charging port of a large UAV.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114784368","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}

Because the RF/DC conversion efficiency of the rectifier circuit has a peak characteristic, not only the output changes with the input power, but also the RF/DC conversion efficiency changes. Therefore, the antenna gain is adjusted to be the input power at which the RF/DC conversion efficiency is maximized for each block divided power receiving antennas. The RF/DC conversion efficiency of the entire power receiving antenna can be improved by making the power input to each block constant. Additionally, the design of the rectifier circuit can be configured with only one type. In this paper, in order to adjust the antenna gain, we propose a microstrip antenna (MSA) loaded with the stacked metal square rings for operating metal wall. It is cleared the calculated results that the antenna gain can be changed stepwise from 6.7 dBi to 10.1 dBi by changing the number of metal layers of MSA.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121281322","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}

Low-cost sensor hardware and manufacturing together with no-skill installation and commissioning and low maintenance requirements can allow widely distributed sensors for continuous, comprehensive monitoring for structural health, physical health, safety, and industrial and environmental applications. This paper presents a system of RF-powered flexible sensors for building environment sensing with the potential to deliver up to 30% energy savings through improved HVAC controls. The system utilizes a set of electronic hubs that both provide remote power to the sensors and wirelessly relay sensor data to the building management system (BMS). The sensors are flexible electronic labels powered by rectified RF energy received from a hub and can contain multiple printed and conventional sensors including for temperature, humidity, and air quality. The electronic hub includes a programmable multidirectional beam-steering antenna that allows arbitrarily-placed sensors to be automatically located by the system through monitoring of received RF power as a function of transmission angle. The system has achieved extremely low-power operation, wireless sensor data transmission over > 10 meters, remote power delivered across >7 meters and sensor localization to within 0.5 meters.","PeriodicalId":148719,"journal":{"name":"2019 IEEE Wireless Power Transfer Conference (WPTC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124039030","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}

The system uses a time-switching based relaying protocol for EH and information processing at the amplify-and-forward (AF) relay nodes. For it, we formulate an order statistics problem of finding the distribution of maximum energy harvested among several EH relay nodes by considering two different fading models, namely, path loss and Rayleigh fading model, path loss and shadow fading model. For these models, we derive analytical expressions for the mean value of maximum harvested energy distribution. Furthermore, we also present an insightful outage analysis and numerical results to validate the analytical expressions.
