With advances in technology and people’s increasing emphasis on health issues, there has been a rapid development of wearable and implantable biomedical sensors. However, radio frequency waves dominate wireless communications, despite disadvantages such as high attenuation in the human body, considerable power consumption, and complicated wireless antenna design, which has hampered the developm...

Low-profile coplanar waveguide antennas are successfully designed considering body-centric communications requirements. A finite difference in time-domain-based programme, which considers dispersion human tissues and antenna dielectric substrates, is developed for this purpose. Parametric simulations visualisation helped to acquire a greater understanding of radiation mechanisms. Consequently, ...

The miniaturization of electronic devices is leading to the creation of body-centric wireless communications (BCWCs), in which wireless devices are attached to the human body. In particular, personal healthcare is considered as the biggest potential application. In this paper, we propose a compact wearable dual-mode (on-body and off-body modes) antenna for personal healthcare systems. For on-bo...

Recently, wearable wireless devices or terminals have become hot a topic not only in research but also in business. Implantable wireless devices can temporarily be utilized to monitor a patient’s condition in an emergency situation or to identify people in highly secured places. Unlike conventional wireless devices, wearable or implantable devices are used on or in the human body. In this sense...

Wireless communications are radically changing the way we communicate and live. While wireless communications for, e.g., computers communications and cellular telephony are a commodity nowadays, another important paradigm (an extension of the above technologies) is entering our lives, which are wireless sensor networks. In particular human centered networks of this kind are going to play an imp...

To clarify mechanisms involved in the human recognition of body-mediated information, this study examines what kinds of impressions and emotions are perceived from body movements in dance. The study attempted to develop multiple regression models to investigate the effects of physical movement factors on impressions and emotions. The regression analyses show that people perceive emotional infor...

Wearable wireless networks (WWNs) offer innovative ways to connect humans and/or objects anywhere, anytime, within an infinite variety of applications. WWNs include three levels of communications: on-body, body-to-body and off-body communication. Successful communication in on-body and body-to-body networks is often challenging due to ultra-low power consumption, processing and storage capabili...

A body area network (BAN) is a network of bodyworn or implanted electronic devices, including wireless sensors which can monitor body parameters or to detect movements. One of the big challenges in BANs is the propagation channel modeling. Channel models can be used to understand wave propagation in and around the human body and they are essential for antenna design, protocol design and the des...

introduction: the nursing staff, compared to other professions, have less healthy work environment and always face a lot of job stress. the quality of the relationship between nurses and physicians has a significant impact on nurses. thus, the aim of the present study was to determine the correlation between job stress for nurses with professional communication between nurses and physicians. ma...

the intelligent transportation system (its) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. this system consists of many fixed and mobile nodes (vehicles, trains, vessels, air planes), wireless and wired telecommunication technologies to exchange information between mobile nodes or betwee...
