Biocompatible material of SU8 is employed in coating since the antenna is designed to work in human body. By using the meandering strategy, the size of the proposed antenna can be significantly miniaturized compared with the state-of-art ones at the operating bands (radius of 5.5 mm and height of 0.645 mm). The simulated bandwidths are 105% and 20% in MICS and ISM bands, respectively. The SAR and total efficiency are also simulated in CST human model and show excellent performances.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"7 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89016996","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}

Some examples are pacemakers, implantable defibrillators, bionic eye, bionic ear, swallowable devices like wireless capsule, neural recording and stimulation devices and wearable sensor devices in telemedicine for physiological signal sensing and monitoring. More body sensor devices will be developed in the future to undertake various body tasks and to diagnose chronic diseases. These devices are made wireless in order to increase patient comfort, to enable patient mobility, and to make the device robust. A wireless system is necessary for information transfer from these devices placed on or inside the body for purpose of controlling and monitoring. A wireless link designed for body sensor devices should form an intelligent communication network such as a body area network in order to work efficiently and safely in the same environment. This article presents recent sensor nodes developed for such medical networks.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"69 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79556511","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}

By enforcing the boundary conditions along metallic surface, the magnetic fields are well confined between two plates and its flux focusing can be also improved. Meanwhile, the large metallic plates can also help to achieve higher transfer efficiency of the wireless power transfer link. Based on the filter theory, these enhanced field intensity effectively enlarge the dynamic range of coupling degree, thus improving the efficiency of the energy transmission. Finally, a 40.68MHz wireless transfer link with the highest measured efficiency of 86.56% is obtained and demonstrated.","PeriodicalId":6321,"journal":{"name":"2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO)","volume":"140 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74901474","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}
