Mobile Application to Collect Data and Measure Blood Component Level in a Non-Invasive Way

The increasing advancement in mobile technology has led to many smartphone-based technologies being widely accepted in various research fields. In recent years, promising smartphone-based technologies have been developed for activity recognition, gait analysis, telemedicine, and fitness tracking. However, some invasive methods are used for measuring blood components (hemoglobin, glucose, bilirubin, etc.). This invasive method involves drawing blood from patients and then analyzing the blood sample. This process is painful, and the time delay between the blood collection and analysis can be a significant disadvantage. Extensive research is being conducted to introduce a noninvasive method of measuring blood components. However, these methods may be expensive and inconvenient for people with little literacy. To deal with these issues, we have developed a mobile application that any group of people can use conveniently and quickly. Furthermore, this application can collect data without causing inconvenience and output blood glucose and hemoglobin levels, allowing for real-time data monitoring. A study evaluated the system’s performance, comparing invasive and noninvasive hemoglobin measurements on 15 subjects (11 male, 4 female) using this app. It was also tested on Samsung, Realme, Vivo, and Redmi phones, showing compatibility with diverse brands.
