1. MULTI-PLATFORM WIRELESS MEASUREMENT SYSTEM
FOR CONTINUOUS BIO-MONITORING
ABSTRACT:
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.
