Recent developments in capsule endoscopy have highlighted the need for accurate techniques to estimate the location of a capsule endoscope. A high accuracy localization of the order of millimeters is required for endoscopic applications. Location estimation of a capsule endoscope in the gastrointestinal (GI) tract is a challenging problem, as radio frequency signals encounter a high loss and highly dynamic channel propagation environment. In this paper, the characteristics of radio frequency signal absorption inside the human body are investigated with the aim of developing an accurate propagation model. Furthermore, the possibility of using a radar system for capsule localization is investigated and compared to its operation in the 2.4G Hz ISM band.

Wireless Body Area Network (WBAN) plays an important role in real-time data gathering by on-body vital sensors for athletes in a sports training scenario. However, the 2.4 G Hz Industrial, Scientific and Medical (ISM) band, which is one of candidate frequency bands for WBAN, is not rich in diffraction, so when a man putting on on-body sensor nodes and a BAN coordinator takes different postures and actions, the direct links between them are frequently blocked by parts of his body, resulting in a higher packet error rate (PER). This paper proposes a cooperative relaying scheme for lowering the PER in a WBAN. For each node on a human body, the proposed scheme autonomously assigns a node as a cooperator out of other nodes and the cooperator re-transmits packets from the node for a BAN coordinator instead when the direct link between them is blocked. The paper evaluates the performance of the proposed scheme in terms of average and worst outage rates using experimental data for three subjects in a mixed indoor/outdoor environment.
无线体域网络(Wireless Body Area Network, WBAN)在运动员运动训练场景中通过身体上的生命传感器实时采集数据方面发挥着重要作用。然而，作为WBAN候选频段之一的2.4 G Hz工业、科学和医疗(ISM)频段的衍射并不丰富，因此当佩戴传感器节点的人与BAN协调器采取不同的姿势和动作时，它们之间的直接链接经常被身体的某些部位阻塞，从而导致更高的分组误码率(PER)。提出了一种降低无线局域网PER的合作中继方案。对于人体上的每个节点，该方案从其他节点中自主分配一个节点作为协作者，当它们之间的直接链路被阻塞时，协作者将来自该节点的数据包重新传输给BAN协调器。本文利用室内/室外混合环境中三个受试者的实验数据，从平均中断率和最坏中断率方面评估了所提出方案的性能。

Several studies have reported that bone-conducted ultrasounds (BCUs) can be perceived even by those with profound sensorineural deafness, who typically hardly sense sounds even with conventional hearing aids. The perception of BCUs by the profoundly deaf has been objectively proven using magnetoencephalography (MEG). Furthermore, both the psychological characteristics and the neurophysiological mechanisms underlying the perception of BCUs have been identified by psychophysical, electrophysiological and physical approaches. In addition, we have developed a BCU hearing aid (BCUHA) for the profoundly deaf. Remarkable results have already been achieved with this device, which enabled 42 % of the profoundly deaf subjects in the trial to perceive some sort of sound and 17% of them to recognize simple words. These results suggest the feasibility of this device, but additional development and improvements are needed.

Considerations of biological effects, executed as the bio-heat and bio-thermal simulations, in terms of a specific absorption rate (SAR) and temperature rise in human body tissues for ultra wideband (UWB) wireless body area network (WBAN) applications are studied in this paper. 3D-electromagnetic (EM) simulation software, utilizing finite integration technique (FIT), is used in order to obtain temperatures and power losses by thermal stationary and transient solvers (TSS, TTS) in the vicinity of the modelled dispersive medium. Two different UWB antennas having excellent radiation properties are experimented on contact with tissues. The effect of the antenna input power on the temperature and maximum SARs over 1 g and 10 g averaging masses are evaluated. Obtained results are compared with the restrictions set by the institute of Electrical and Electronics Engineers (IEEE) and International Commission on Non-Ionizing Radiation Protection (I CNIRP). This paper investigates generally how much power should be fed to the UWB antenna in order to cross the maximum SAR limits in WBANs or in order the antenna start to heat the tissues significantly, both in the stationary conditions and further as the transient solutions.

This paper proposes and investigates an novel hybrid ARQ type of error control scheme using Weldon's ARQ in order to satisfy different requirement of QoS in medical and nonmedical data for wireless body area networks (WBANs). Although an international standard of WBANs has been established as IEEE802.1S.6 in February 2012, its optional hybrid ARQ scheme has not properly designed so that error detecting and correcting capabilities and permissible delay can be optimized for each requirement of 7 different QoS modes. The proposed scheme employs decomposable codes in order to adjust balance between error-correcting capability of codes and number of retransmission according to each QoS. Numerical results illustrate the proposed scheme can improve BER and throughput performances satisfying each QoS.

Wireless body area network (BANs) have attracted a lot of attention as a future technology of wireless networks. Wireless BANs are generally divided into two kinds of groups, i.e., on-body BANs and in-body BANs. However, the performance requirements and channel propagation characteristics of the two BANs are quite different from each other, that is, wireless signals are approximately transmitted along the human body as a surface wave in on-body BANs, on the other hand, the signals are transmitted through the human tissue in in-body BANs. As a solution for this problem, this paper develops a structure of dual-mode transceivers, which is composed of transmitters for in-body and on-body communications and a receiver for the both communications. Then, we evaluate the communication performance of the dual-mode transceivers via a computer simulation with realistic channel models, which can well represent the propagation characteristics of on-body and in-body communications. Our computer simulation results demonstrate the feasibility of the dual-mode transceiver structure in wireless BANs.

We investigated the advantages and drawbacks of wireless body area network (BAN) systems using high-band ultra-wide band (UWB) wireless technology for healthcare. These systems are expected to have robustness against interference, low power consumption, and little interference from a human body. The most serious drawback is the shadowing problem due to a body in a hospital or home care bed. We confirmed by experiments and theoretical analysis that setting a coordinator near the ceiling and another coordinator under the bed is one of the best measures to prevent the shadowing problem. In this study, a shadowing model was used. A helical antenna having high antenna gain in the axial direction was used in the coordinator. In comparison with a biconical antenna, the helical antenna showed better radiation performance and less dependence on the angle direction of the antenna of the sensor node.

A self-powered urinary incontinence sensor with a flexible wire-type urine-activated battery that is embedded in a diaper has been developed as an application for wireless biosensor networks. Since the battery is flexible, it conforms to the shape of the diaper when the diaper is worn. The stress produce by the curvature presses the electrodes firmly against the diaper material, providing greater contact with any urine present. Thus, due to the curvature, the battery generates more power than when it is flat, as in an unworn diaper. The battery also acts as a wide ground plane for the antenna of a wireless transmitter, providing a large radiated power. To verify the effectiveness of the battery, we fabricated a battery and a prototype sensor and embedded the battery in a diaper. When 80 cc of urine is poured onto the diaper, the battery outputs a voltage of 1 V, which allows the sensor to transmit an ID signal over a distance of 5 m.

To prevent stroke, it is necessary to identify the symptoms of a transient ischemic attack (TIA) quickly and to be treated at special medical facilities. A stroke neurologist has been conducting stroke education lessons for teens. However, efficiently conveying the information is difficult because the lesson has some limitations, including a shortage of physicians who can present the information. In this study, we have developed an online support system that enables schoolteachers to provide stroke education. This is a new approach. By using our system, schoolteachers can lecture to students on stroke signs, risk factors, symptoms and the FAST message (Facial droop, Arm weakness, Speech disturbance and Time of emergency call) for identifying typical symptoms of TIA. Additionally, we provide a web-based questionnaire survey for checking students' knowledge level. As a trial run of the system, we conducted a test lesson involving 78 students and a schoolteacher in a public junior high school. It was confirmed that the lesson could be conducted without trouble. On average, 70% of all students answered a question about the FAST message correctly. It was suggested that the function of the management side needs to be improved to increase the accuracy of the answer data. Our system could be used as a support tool for stroke education.
