Their importance becomes more significant for in/on-body wireless applications. Body Area Network (BAN) links lead to propagation problems considerably different from free space wireless communications due to presents of body tissues, body movements, and enormous figure of body poses. Therefore, to ensure the efficient performance of body area wireless communication the electromagnetic wave propagation need to be characterized and modeled for reliable communication system with respect to environment, antenna, body postures, and body movements. This paper discusses on polarization mismatch due to body movements between on-body transmitting antenna and off-body receiving antenna.","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":"60 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":"82546961","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}

Due to path loss and restriction on permissible transmission power; the RF power available to the input of the RF energy harvesting system is relative low. In this work, we present a study of ambient RF energy harvesting. We also explore to determine whether another emerging technology wireless power transfer can be integrated with RF energy harvesting. A measurement of the ambient RF power density on GSM 900 and GSM 1800 bands in Nanyang Polytechnic of Singapore is presented. From our conclusion, the harvested energy is not able to directly power the wireless sensor network; however the harvested energy can be stored in a super-capacitor and over some time it can be used to power on the wireless sensor network. So, is RF energy harvesting ever going to become a practical reality? The answer is a cautious yes.","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":"16 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":"79657403","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}

In order for the implanted device is able to be used in longer range transmission, the device is wirelessly transmitted in the form of electromagnetic signals. This initiates us to study on a patient home monitoring system, in which the external devices such as portable equipments will provide a benefit for healthcare provider in accessing the important patient medical information via a networked connection. Because of this reason, an electrically small antenna for implantable devices is very essential components in monitoring systems to provide wirelessly communication between a patient and an access point. In this paper, a helical folded dipole antenna for an implantable device is proposed for wireless patient monitoring system. The implanted device is assumed to be applied by a syringe injection allowing to the device is simply injected into the human body. The proposed antenna is operated in UHF band 924 MHz, as a band of Indonesian RFID applications. The antenna is quite small in comparison to the band operation (ka≈0.08). Sufficient electrical performances are obtained such as reflection coefficient, impedance bandwidth, radiation pattern and gain. According to the link budget analysis, the proposed antenna has adequate gain within 10m transmission range by 225 MHz bandwidth (VSWR ≤ 2).","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":"5 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":"74416491","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}

An application of microwave energy to drill a hard cortical bone is even though proposed by some researchers but an investigation of thermal interaction at a drill site is still remain promising especially in a term of simulation. This research investigates a microwave thermal ablation for bone drilling through a 3D FEM solver. Microwave drill applicator was designed as an opened-tip coaxial antenna which inserted into a center of cortical bone model.
