“…One of the metal oxides commonly used for the detection of exhaled acetone is tungsten oxide (WO 3 ), which has n-type conductive behavior with a catalytic effect both in the oxidation and reduction reactions on its surface. Recently, Muñoz and Rodríguez [ 52 ] used colloidal processing (slip casting) to control the elaboration of sensitive materials, that is, macroporous bodies based on WO 3 . These pieces showed good sensitivity to acetone vapors at concentrations above 1 ppm and at 250 and 300 °C.…”

Metal oxide (MOx) gas sensors have attracted considerable attention from both scientific and practical standpoints. Due to their promising characteristics for detecting toxic gases and volatile organic compounds (VOCs) compared with conventional techniques, these devices are expected to play a key role in home and public security, environmental monitoring, chemical quality control, and medicine in the near future. VOCs (e.g., acetone) are blood-borne and found in exhaled human breath as a result of certain diseases or metabolic disorders. Their measurement is considered a promising tool for noninvasive medical diagnosis, for example in diabetic patients. The conventional method for the detection of acetone vapors as a potential biomarker is based on spectrometry. However, the development of MOx-type sensors has made them increasingly attractive from a medical point of view. The objectives of this review are to assess the state of the art of the main MOx-type sensors in the detection of acetone vapors to propose future perspectives and directions that should be carried out to implement this type of sensor in the field of medicine.

“…Electrochromic phenomena have a wide range of applications in the fields of smart windows, displays, anti-glare rearview mirrors, smart thermal control and camouflage, etc., [ 5 , 6 , 7 , 8 ]. WO 3 , an electrochromic layer material, has been widely used in inorganic electrochromic and other related technical fields because of its advantages, such as high-color contrast, low manufacturing cost, non-toxicity, and stability under acidic and oxidizing conditions [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”

Most ECDs are coated with an electrochromic material on the transparent conductive oxide (TCO) substrate. A novel electrochromic device (ECD), having a variable optical performance, was prepared by using tungsten foil as a substrate in this study. It was found that the WO3 discoloration layer, having a monoclinic phase crystalline structure made of 600 °C calcined, had optimum charge transmission performance with PADA gel polymer electrolyte. Ionic conductivity of PADA gel polymer electrolyte was 2.3 × 10−3 S cm−1 at −20 °C, and it was possible to help Li+ to implement embedding and extraction from WO3 even in low-temperature conditions. The colored time (tc) and the bleached time (tb) of the electrochromic device were 15 s and 26 s, and it showed yellowish-brown in the colored state and navy blue in the bleached state. The ECD (WO3-600) exhibited good cycle stability reach at least 150 times.
