Abstract: Title: Non-Invasive Glucose Detection Device The disclosed invention relates to a non-invasive glucose detection device that utilizes a dual-cartridge system to accurately analyze glucose levels in biological fluids such as urine or saliva. One cartridge is designed to store a small volume of the user's biological sample, while the other holds a pre-filled reagent—either Fehling’s or Benedict’s solution—known for its colorimetric response to reducing sugars. Upon activation, both fluids are released in controlled volumes using electronically operated microvalves and are directed through microtubing into a thermally regulated reaction chamber. In this chamber, the reagent reacts with any glucose present in the sample, initiating a redox reaction that produces a distinct color change based on the glucose concentration. This colorimetric shift is then captured using an integrated optical sensing module, which may be an RGB color sensor or a spectrophotometric absorbance sensor. The sensor’s output is processed by a microcontroller that executes an AI-trained standard curve estimation module, converting the optical signal into an accurate numerical glucose concentration expressed as a percentage. The result is simultaneously displayed on an LCD screen and indicated via a color-coded LED interface to allow for quick visual interpretation. The device is designed to be reusable, portable, and cost-efficient, making it highly suitable for home use, remote diagnostics, and rural clinical settings. Its compatibility with both urine and saliva samples, automated fluid handling, and intelligent real-time data processing enable rapid and hygienic glucose monitoring without the need for invasive blood sampling or clinical expertise.
