At present, people diagnosed with diabetes need frequent monitoring of their blood to ensure their safety and health. These people rely either on blood chemistry, or the glucometer which are both invasive methods to determine the blood glucose level. Invasive methods require more than just skin contact--it requires methods of pricking (lancets, or syringes) to obtain the desired data. A common example used by diabetic patients is the glucometer. The glucometer makes use of a lancet that is pricked into the skin so that the blood which will be needed in determining the blood glucose of the patient may come out. This may cause problems like infections if the lancet is poorly sanitized, or phobia and discomfort for others who have low tolerances of pain. This study aims to develop a device which non-invasively measures the pulse transit time of a person and correlate it with their blood glucose level. The pulse transit time technique used in this study uses two different points of the body (the wrist and upper arm) to measure the time difference of the pulse travelling between these two distinct points. The signal is then processed by a microcontroller and data is stored in the system's database.
