Breath analysis is an attractive strategy that holds tremendous potential to achieve non-
implantable physical health management enabled by flexible humidity sensors for breathing …

The analysis of volatile compounds is an efficient method to appraise information about the
chemical composition of liquids and solids. This principle is applied to several practical …

The high moisture level of exhaled gases unavoidably limits the sensitivity of breath analysis
via wearable bioelectronics. Inspired by pulmonary lobe expansion/contraction observed …

Detection limit as an important parameter of gas sensors, much effort has been devoted to
developing high-performance gas sensors with low detection limit. However, the …

Despite the enormous development of instruments for analyzing a wide variety of
compounds, applied in different fields such as health, environment or quality control, the …

A flexible NO 2 gas sensor based on a polypyrrole/nitrogen-doped multi-walled carbon
nanotube (PPy/N-MWCNT) composite film was successfully prepared on PI substrates using …

In this paper, we demonstrated a room-temperature acetone gas sensor based on a tin
dioxide (SnO2)-reduced graphene oxide (RGO) hybrid composite film. The SnO2–RGO …

Endowing triboelectric nanogenerator (TENG) with excellent acetone-sensing and humidity-
tolerant property is an effective strategy for prospective breath diagnosis of diabetes without …

In this work, flame-spray-made SnO2 nanoparticles are systematically studied by doping
with 0.1–2 wt% nickel (Ni) and loading with 0.1–5 wt% electrolytically exfoliated graphene …

This paper describes the polymerization of thiophene monomer with various loadings of
chitosan nano-powders via the simple in-situ method. The formation of polythiophene …
