TITLE
braceIO: Biosensing through Hydrogel Dental Ligatures
ABSTRACT
Dental braces are a semi-permanent dental treatment that comes into direct contact with our metabolism (saliva), the food and liquids we ingest, and our environment, while we smile or talk. This paper introduces braceIO, biochemical ligatures on dental braces that change colors depending on saliva concentration levels (pH, nitric oxide, and uric acid), and can be read by an external device. This work presents our fabrication process of the ligatures and external device, the technical evaluation of the absorption time, colorimetric measurement tests, and the color map at the biosensor level in the app. This project aims to maintain the shape, wearability, and aesthetics of traditional ligatures but with embedded biosensors. We propose a novel device that senses metabolism changes with a different biosensor ligature worn in each tooth to access multiple biodata and create seamless interactive devices.
