Wireless electronic systems for physiological parameters measuring

Wireless communication technologies together with physiological signals sensing provide a wide range of capabilities for monitoring, recording and analysis of the physical and health status of individuals. This paper describes two systems using wireless transmission of information designed to measure physiological signals. The first system is system for automatic cardiopulmonary examination measuring and evaluating. The system measures heart rate, pulmonary ventilation, breathing frequency and blood pressure. From these data, many of other standard parameters are calculated. Application of this system is possible in work medicine, sport medicine and rehabilitation. The second system is a system for measuring and wireless transmission of selected physiological signals and variables. The system consists of wireless sensors, data transceivers and information system for the visualization and analysis of measurement data. This paper describes sensor for monitoring of body temperature and RF transceiver, which are being developed as part of the system. Temperature sensor is due to its high demand on low energy consumption not suitable for measuring signals, which will produce large amount of data and therefore consumes more energy on wireless transmission and processing of the data. Due to this reason, this sensor does not measure other signals and measure only temperature so fare. Other sensors, which will measure more physiological signals, like pulse rate, ECG and motion activity of monitored person will be developed in future. Possible use of the sensor or whole system is in a medical environment.
