This paper presents the fabrication of a prototype with unique functionalities for monitoring human heart rate via simple insertion of fingertip on an infrared based sensor. The variation in the absorbance caused by the repeated pumping of oxygenated blood to various tissues within the body leads to distinct peaks and dips corresponding to the signal from the detector. Further, a MATLAB based Graphical User Interface (GUI) is developed to visualize this heart-beat signal as well as count the heart rate. In addition, the oxygen concentration can also be deciphered from the reported sensing scheme. The developed prototype seems to be in excellent match with standard heartrate monitoring device. It is believed that this multimodal prototype will pave way for more investigation towards development of sophisticated AI based analysis.
