A novel heart rate and non-invasive glucose measuring device

摘要

At the cross section of the fields of biomedical devices and signal processing, is the work of a novel heart rate and non-invasive blood glucose measuring device capable of measuring these vital medical parameters in parallel. This paper describes different non-invasive methods used to measure these parameters involving concepts from signal processing. The concept of Near Infrared (NIR) photoplethysmography is used to measure the change in the light absorbed by illuminating the skin to compute the pulse rate of a person combined with the help of a proposed novel algorithm while blood glucose is measured optically with the help of an Infrared LED (wavelength of 940nm) in which the amount of light received by the photodiode determines the glucose concentration in the blood. The paper focuses on making a remote, cost effective device capable of efficient measurement combined with a user-friendly GUI. The proposed device also uploads the measured values on the cloud for authentic diagnosis by physicians for far-away patients' lacking state of the art diagnosis.
