Abstract:Introduction
Environmental safety is attracting significant attention due to the increase of dust particles, and toxic gas species (e.g. CO, NOx, etc.) [1]. CO is identified as a major threat for human health. Since CO is a colorless, odorless, and tasteless gas, it can't be detected by human senses. Therefore, sensitive sensor operating in humid air is required for CO gas detection [2]. For metal oxide (MOX) gas sensors, the humidity interferes with the low-level detection of r… Show more
“…Consequently, the bilayer device displays a dual-action mechanism, leading to substantial shifts in the electrical resistivity of the sensor when exposed to VOCs. [49][50][51][52][53]71 The presence and concentration of VOCs can be detected and quantified accurately because of the change in resistivity. The accurate detection of VOCs under ambient conditions and the SnO-BaTiO 3 bilayer sensor's robust performance at room temperature are crucial for real-world gas sensing applications.…”
