Abstract
An indication of the dental health of patients can be
observed from the pH levels of their saliva. This work presents
a first prototype of a smart Orthodontic Bracket (SOB) for
continuous monitoring of pH in mouth. The SOB system uses
Iridium Oxide (IrOx) pH sensor with 68.8 mV/pH measured
sensitivity and is powered through Near Field Communications
(NFC) using a smart-phone from a distance of 3.5 cm. The system
resolves pH change of 0.15 within a wide range of pH. The system
is encapsulated in bio-compatible Epoxy resin and successfully
used to measure the pH in Saliva.
