Plain English summary

This review discusses mechanochromic materials that change color in response to mechanical strain, making them suitable for smart textiles. These materials can provide real-time feedback without the need for electronic components, which is beneficial for activities like yoga and rehabilitation that involve subtle movements. The paper evaluates various integration strategies for these materials into textiles and compares different mechanochromic platforms based on their performance.

Why this matters

This research addresses the limitations of conventional electronic wearables in low-intensity exercises, where power consumption and complexity can hinder usability. By exploring mechanochromic materials, the study highlights a potential solution for enhancing proprioception and movement precision in rehabilitation and exercise, which could significantly improve user experience and outcomes.

Key findings

  • Mechanochromic materials provide real-time, energy-free visual feedback.
  • They are suitable for low-intensity movements in exercises like yoga and rehabilitation.
  • The review evaluates textile integration strategies such as coating and fiber spinning.
  • Key platforms include polymer-based systems and cholesteric liquid crystal elastomers.
  • A user-centered application framework for smart garments is proposed.

What's new

The review connects material innovation with specific application demands for nonelectronic smart garments in low-movement scenarios.

Limitations

The abstract does not provide experimental results or specific case studies demonstrating the effectiveness of the proposed materials and strategies.

Commercial context

The abstract does not mention any commercial availability or readiness of the materials discussed.
