Area of Science:

  • Materials Science
  • Nanotechnology
  • Sensor Technology

Background:

  • Developing chemically responsive, nonconductive textiles for sensors is challenging.
  • Existing fibrous materials lack the structure sensitivity needed for reliable sensing.

Purpose of the Study:

  • To create a fibrous platform with enhanced structure sensitivity for chemical sensing.
  • To demonstrate the material's responsiveness to alcohol molecules for breath and sweat analysis.

Main Methods:

  • Electrospun polymeric fibrous substrate embedded with gold nanoparticles and dendrons.
  • Tuning nano-filament assembly to control interparticle properties and structure sensitivity.
  • Testing chemiresistive responses to various alcohol vapors in high-moisture conditions.

Main Results:

  • The material exhibited high structure sensitivity to molecular interactions.
  • Chemiresistive responses to alcohol molecules scaled with chain length and varied with isomers.
  • Demonstrated potential for multiplexed sensing in a sensor array format.

Conclusions:

  • The developed fibrous platform enables chemically responsive electro-functionality in textiles.
  • This approach offers a paradigm shift for designing textile sensors for human performance and environmental monitoring.
  • High structure sensitivity is key for multiplexing and accurate sensing in complex backgrounds.
