DESCRIPTION

The work aims to provide a portable and a non-invasive innovative health monitoring system utilizing infrared light. The device detects necessary vital signs particularly heart rate (bpm), blood oxygen saturation (SaO2), blood glucose (mg/dL), and body temperature (°C) from the fingertip of the user. The device does not require pricking or any other invasive methods such as implants, which minimizes the risks of infection. Sensors were calibrated and interpreted by Arduino microprocessing unit, with a pulse oximeter sensor for reading both heart rate and blood oxygen saturation, a temperature sensor for the body temperature, and an infrared reflective sensor for blood glucose interpretation using near infrared optical method. Device signals were then sent to the android phone application via Bluetooth connectivity, which allows the user to record and keep track of the data. Testing revealed that the fabricated device was capable of transmitting real time data. Results also suggest that a non-invasive strategy of monitoring health parameters was successfully introduced with an accuracy of 98.6% for heart rate, 98.2% for SpO2, 96.1% for body temperature and 89.9% for blood glucose. An unpaired t-test was conducted for the blood glucose (p>0.01). The result suggests that there is no significant difference between the device and commercial products measurements. The results also show that the device is capable of providing accurate real-time vital sign information, which means that the device can be an alternative non-invasive health monitoring system.
