Vital signs monitoring system using FPGAs

We developed a mobile device using field programmable gate arrays (FPGAs) to detect and monitor basic human body functions, such as, body temperature, blood pressure, heart rate and respiratory rate. This information can give a clue to a possible diagnosis and display a recovering progress in treatment. We designed the digital circuits and electronic components tested and simulated them with using Very-High-Speed Integrated Circuit Hardware Description Language (VHDL). Synthetic circuits were then downloaded into chip on our developed circuit broad and all electronic components were built up together. A low-cost in-house device was completely made as a reconfigurable system. We successfully used our vital signs devices to measure body temperature, blood pressure, pulse rate and respiratory rate. Further development, we will design and customise our existing device to be smaller in its size and much easier to handle.
