Design and Study of a Wearable Non-Invasive Photoacoustic Glucose Monitor
Abstract
This paper relates to a wearable non-invasive photoacoustic blood glucose monitor with a display, control buttons, controller, battery and measurement box in a wearable housing. The wearable case is fitted with a strap that is worn on the wrist of the person being tested. The photoacoustic excitation source and the optical lens system produce a focused laser beam that passes through the hollow multi-ring array sensor and is directed towards the blood vessels in the wrist to achieve continuous A-shaped dynamic focus scanning photoacoustic glucose detection, providing photoacoustic glucose results at multiple sites in the depth direction of the wrist. This paper has the advantages of being compact, portable, easy to operate, enabling real-time monitoring of photoacoustic glucose, non-invasive during testing, eliminating the need to extract blood and provide test strips, and avoiding cross-contamination and environmental effects.
