Vücut Alan Ağları, uzaktan sağlık izleme ve nesnelerin interneti konularının temel bir parçası olarak günümüz bilim dünyasında yerini almıştır. Vücut üzerinde, çevresinde ya da içinde yeralabilen algılayıcı düğümlerin ölçtüğü sinyaller bu ağa sahip bireylerin sağlığı hakkında bilgileri aktarmaktadır. Vücut Alan Ağları'nın diğer ağ tiplerine benzer problemleri bulunmaktadır ve bu problemlerin başında enerji tüketimi gelmektedir. Vücut Alan Ağları genellikle kablosuz iletişim yapmakta ve kişinin hareket halindeyken de düğümlerin ölçüm yapması için enerji birimlerine (pil, akü vb.) ihtiyaç duymaktadır. Bu sebeple enerji ünitesinin her zaman değiştirilebilmesi mümkün olmamaktadır. Bu çalışmada Vücut Alan Ağı'nın enerji problemini ortadan kaldırmak için enerji hasadı ünitesi geliştirilmiştir. Piezoelektrik malzeme ve peltierden oluşan bu ünite Vücut Alan Ağı'nın enerji ihtiyacını karşılamaktadır.

Wireless body area network (WBAN) is a term used to describe a network of sensor devices connected wirelessly for communication on, in and near the body to obtain physiological data from sensor devices. This paper explain the implementation of WBAN for monitoring body temperature, heart beat rate and oxygen saturation in blood. We develop the sensor reads physiological data to the desktop application, then will read the printout of the series and create a visual in the tables and graphs, as well as storing the data into a database and displayed via a website in the form of reports that can be accessed remotely. We analyze the data received from sensor nodes to server receiver with a variety of different distances 10, 20, 30, 40, and 50 meters. The experiment results show that the physiological data can be accessed through ZigBee wirelessly in short distance which suitable for WBAN.

Abstract:Energy harvesting has become a promising and alternative solution to conventional energy generation patterns to overcome the problem of supplying autonomous electrical systems. More particularly, thermal energy harvesting technologies have drawn a major interest in both research and industry. Thermoelectric Generators (TEGs) can be used in two different operating conditions, under constant temperature gradient or constant heat flow. The commonly used TEG electrical model, based on a voltage source in series with an electrical resistance, shows its limitations especially under constant heat flow conditions. Here, the analytical electrical modeling, taking into consideration the internal and contact thermal resistances of a TEG under constant temperature gradient and constant heat flow conditions, is first given. To give further insight into the electrical behavior of a TEG module in different operating conditions, we propose a new and original way of emulating the above analytical expressions with usual electronics components (voltage source, resistors, diode), whose values are determined with the TEG's parameters. Note that such a TEG emulation is particularly suited when designing the electronic circuitry commonly associated to the TEG, to realize both Maximum Power Point Tracking and output voltage regulation. First, the proposed equivalent electrical circuits are validated through simulation with a SPICE environment in static operating conditions using only one value of either temperature gradient or heat flow. Then, they are also analyzed in dynamic operating conditions where both temperature gradient and heat flow are considered as time-varying functions.
