Area of Science:

• Materials Science
• Nanotechnology
• Textile Engineering

Background:

• High-temperature textile pressure sensors are crucial for applications in harsh environments.
• Existing sensors often lack durability and high-temperature resistance.
• Developing robust sensors for extreme conditions remains a significant challenge.

Purpose of the Study:

• To provide a cost-effective fabrication method for high-performance textile sensors.

Main Methods:

• Fabrication of textile pressure sensors utilizing multi-wall carbon nanotubes (MWCNTs) and quartz fabrics.
• Testing sensor performance under cyclic loading to evaluate fatigue resistance.
• Assessing sensor functionality and sensitivity at elevated temperatures (up to 300 °C) and after high-temperature calcination (900 °C).

Main Results:

• The developed textile pressure sensors demonstrated low fatigue over 20,000 cyclic loadings.
• The sensors maintained good sensitivity and functionality at temperatures up to 300 °C.
• Excellent thermal stability was observed, with sensitivity preserved after calcination at 900 °C in N₂.

Conclusions:

• A facile and inexpensive method for creating high-temperature resistant textile pressure sensors was successfully demonstrated.
• The combination of MWCNTs and quartz fabrics offers a promising approach for durable, high-performance sensors in extreme conditions.
• This work paves the way for advanced textile-based sensing solutions in demanding industrial and environmental applications.
