Towards a low cost open architecture wearable sensor network for health care applications

Wireless sensor networks present a growing interest in health care applications since they can replace wired devices for detecting signals of physiological origin and continuously monitoring health parameters, offering a reliable and inexpensive solution. In this paper a low cost open architecture wearable sensor network for health care applications is presented. Through this study, an experimental wireless sensor network (WSN) architecture has been built from scratch in order to investigate and present the development procedure and the corresponding capabilities and limitations of such a system. Moreover, technological aspects regarding implementation are also presented.
