This paper presents the implementation of a simple, compact, and cost-efficient non-invasive device for Blood Glucose Monitoring (BGM), addressing the drawbacks of invasive techniques. Current BGM methods require a finger-prick blood sample, which is painful and carries the risk of infection. However, this new technique, known as Red Laser Blood Glucose Monitoring (RL-BGM), utilizes visible red optical laser light with a wavelength of 650 nm, offering the superior potential for accurate BGM. Existing BGM techniques based on Near-infrared (NIR) have limitations, including light absorption in human tissue, a higher signal-to-noise ratio (SNR), and reduced accuracy. Consequently, NIR methods have not been widely adopted for commercial BGM applications. The proposed RL-BGM device is developed to overcome these challenges, eliminating the need for invasive procedures and enhancing accuracy. This non-invasive device offers several advantages by utilizing visible red optical laser light. It is simple to use, requiring no finger pricking, and provides a compact design for convenient handling.Additionally, it is cost-efficient, making it accessible to a broader range of users. In conclusion, this paper introduces a novel approach to BGM, the RL-BGM technique, demonstrating promising potential. Implementing a non-invasive device utilizing visible red optical laser light at 650 nm wavelength opens up new possibilities for accurate and convenient blood glucose monitoring, overcoming the limitations of invasive techniques and existing NIR-based methods.
