FPGA-based system for countinous monitoring of three vital signs of human body

This paper has major aim to design a low cost, low power, reliable, and easy to use biomedical instrumentation which can either monitoring or measuring three human body vital signs, i.e. body temperature, heart rate, and respiratory rate. The developed system uses a fingertip optical sensor to measure heart rate and thermistor to detect breathing and body temperature. The designed circuit was simulated using Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) and later synthesized into Spartan-3 FPGA development broad. The test result shows that the developed system successfully obtains 96% accuracy in measuring the three human body vital signs.
