Abstract

Over the last decade the continuous improvements in sensor technologies, connected with recent hardware reconfigurable devices evolution, enable engineers to merge sensors and reconfigurable devices to develop new applications or to improve the existing ones. The miniaturization and integration of multiple sensors in one chip and the increase of precision, stability and power efficiency allow sensors to play an even more important role in medical technology with the main objective of building more accurate and smaller devices that help medical personal to monitor human biomedical parameters. This paper describes a secured wireless system design and implementation. The proposed system consists in one or more wearable sensor nodes that measure human biomedical parameters and then sends the collected data to a base station in order to be analyzed by qualified personal. This system can be used to monitor patient state-of-health or to supervise military personal in training or even in battles, because the new system uses secured transmission. The typical monitored parameters are body temperature, blood oxygen level, heart rate, respiratory rate, movement and position of the subject, but it can be extended and more other different sensors such as cameras or microphones can be added. Reconfigurable devices are used to process data in both sensor node and base station in an innovative environment. Keywords: biomedical parameters, reconfigurable devices, sensor nodes, wireless.
