Abstract

The paper presents and discusses works carried out both at Yerevan State University and abroad on non-invasive metal oxide sensors (chemiresistors) for acetone exhaled by a diabetic. The technologies and parameters of chemiresistors based on tin dioxide, tungsten trioxide, zinc oxide, Fe₂O₃, In₂O₃ and TiO₂ developed at YSU and in the world are presented. Most likely, it makes sense to start investigations start with concentration 1 ppm acetone, non-invasive metal oxide sensors, diabetes, response. The response of the MWCNT-doped SnO₂ chemiresistors was measured at a concentration of acetone from 1 to 12 ppm, characteristic of diabetics at a relatively early stage of the disease.

呼出丙酮上的非侵入式金属氧化物传感器

摘要

本文介绍并讨论了在埃里温州立大学和国外开展的针对糖尿病患者呼出丙酮的非侵入性金属氧化物传感器（化学电阻器）的工作。介绍了学校和国际上开发的基于二氧化锡、三氧化钨、氧化锌、Fe ₂ O ₃、In ₂ O ₃和TiO ₂的化学电阻器的技术和参数。最有可能的是，从浓度为 1 ppm 的丙酮、非侵入性金属氧化物传感器、糖尿病、反应开始调查是有意义的。在 1 到 12 ppm 的丙酮浓度下测量了 MWCNT 掺杂的 SnO ₂化学电阻器的响应，这是糖尿病患者在疾病相对早期阶段的特征。
