Abstract

A first prototype of a Smart Orthodontic Bracket (SOB) for continuous in-mouth pH monitoring is presented in this paper. The SOB system uses an Iridium Oxide (IrOx) pH sensor with 68.8 mV/pH measured sensitivity. It is powered through Near Field Communications (NFC) using a smartphone from a distance of 3.5 cm. The system resolves pH variations as small as 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.

一种用于连续口腔pH监测的无线系统

本文介绍了用于口腔内连续pH监测的智能正畸支架(SOB)的第一个原型。SOB系统使用氧化铱(IrOx) pH传感器，测量灵敏度为68.8 mV/pH。它通过近场通信(NFC)供电，在3.5厘米的距离上使用智能手机。该系统可在广泛的pH范围内分辨小至0.15的pH变化。该系统被封装在生物相容性环氧树脂中，并成功用于测量唾液中的pH值。
