Multi-platform wireless measurement system for continuous biomonitoring

This contribution presents new multi-protocol wireless measurement system for continuous biomedical monitoring of human body parameters. The main goal is monitoring of selected physiological processes that might be very useful in health care and monitoring during sport activities. The monitoring device, based on an on-body sensor, is designed with respect to small size, low power consumption as well as interoperability. Therefore, it is equipped with a microcontroller with RF module for ZigBee PRO or ANT+ networks. Measured data is sent through the wireless network to an acquisition point, which collects the data and transfers it to a database server. Here, the data is stored and can be accessed remotely via internet. This system is mainly aimed at home health care, so it should be able to communicate with standard personal devices such as cellphone, notebook/netbook, PC, tablet, etc. For this reason, the acquisition point is able to communicate via Bluetooth standard as well as Bluetooth low energy (for future use). Through this network, user can view live data as well as data stored in the database server. As an example, the system for monitoring of psycho-galvanic reflex of the human skin will be shown. The communication between the acquisition point and sensor is based on ZigBee PRO network and communication between the acquisition point and visualization device uses Bluetooth network, since recently, this is the most common interface used in portable devices.
