摘要
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.
