Abstract
The goal of this research is to develop a wireless physiological monitoring system and to test its performance. The wireless physiological monitoring system was implemented on an internet-based software environment to allow for data acquisition, transmission and analyses. This wireless physiological monitoring system can be divided into four subsystems; a physiological signal sensor component, a microprocessor, a bluetooth wireless module and an integrated software. The physiological signal sensor component is composed of electrode patches and an instrumentation amplifier. Electrode patches is attached to the patient’s heart area. After the electrode patches receive the signal from the heart, the differential signal is measured and then amplified and filtered for the final output of ECG signal. The ECG signal is transmitted to the program running on a personal computer via bluetooth wireless module to capture those signals for future analysis and processing. The microprocessor uses its ADC (analog to digital converter) to process the analog signals received from the physiological signal sensor component and convert it to hexadecimal digital code. The bluetooth wireless module transmits those signals back to the server wirelessly. The integrated software system then converts those digital signals into wave signals and presents them on the monitoring screen simultaneously. On the other hand, the integrated software system also conforms to the server’s setting and presents these data on the websites so that physician and nurses can use the internet browser to get the most recent info of the monitoring system. This physiological monitoring system can monitor three patients at a time and can be extended to more patients. The size of each portable hardware is about 90×55×20 mm3. This portable hardware can detect patient’s ECG signal, heart rate, and body temperature.
