Submersible touchless interactivity in conformable textiles enabled by highly selective overbraided magnetoresistive...

Area of Science:

• Materials Science
• Wearable Technology
• Sensor Technology

Background:

• Traditional electronics struggle with textile integration due to inflexibility.
• Existing wearable sensors often lack durability and comfort for seamless fabric incorporation.
• There is a need for robust, integrated electronic functionalities within everyday textiles.

Purpose of the Study:

• To develop touchless interactive capabilities within textiles.
• To integrate 1D overbraided magnetic field sensors into fabrics without compromising performance.
• To create machine-washable, conformable sensors for reliable human-textile interaction.

Main Methods:

• Utilized 1D overbraided giant magnetoresistive (GMR) sensors for magnetic field detection.
• Developed an integration strategy that preserves sensor flexibility and fabric comfort.
• Tested sensor performance in various environmental conditions, including humidity and submersion.

Main Results:

• Achieved machine-washable and conformable textile-integrated sensors.
• Demonstrated high sensor detectivity (down to 380 nT) with nearly isotropic response.
• Showcased reliable touchless interactivity in humid and underwater environments.
• Developed functional prototypes: a virtual reality navigation armband and a self-monitoring safety helmet strap.

Conclusions:

• Overbraided magnetoresistive sensors offer a viable solution for integrating touchless interactivity into textiles.
• This technology bridges the gap between rigid/on-skin electronics and comfortable, interactive fabrics.
• Enables new possibilities for interactive textiles in entertainment, safety, and sportswear applications.
