Heart Rate Monitoring system using IR-photodetector sensor

One of the fastest growing fields of the technology -a field of astounding recent achievements and even more promising hopes is biomedical engineering. Laboratory instrumentation, medical imaging, cardiac pacemakers and artificial limbs are some of its familiar products. The principles and techniques of engineering to solve problems in biology and medicine, biomedical engineering today holds an important place as a means of improving medical diagnosis and treatment, as a business and an academic discipline. Design of the health monitoring system is the vibrant topic for the researchers. Different health monitoring systems were designed based on requirement. Heart patients who need daily check-ups will find Heart Rate Monitoring system very useful. Our intension of the work is to make a Heart Rate Monitoring (HRM) system. In this work we have uses the concepts of different branches of electronics namely solid state electronics, digital electronics to design a biomedical device that will measure the heart rate of a person from his fingertip using IR-photodiode sensor pair.
