Mutable Collagenous Tissue: A Concept Generator for Biomimetic Materials and Devices

Area of Science:

• Biomaterials Science
• Echinoderm Biology
• Biomimetics

Background:

• Echinoderms possess a unique mutable collagenous tissue (MCT) with rapidly adjustable mechanical properties.
• Research on MCT spans over 50 years, inspiring biomimetic designs for over 20 years.
• Sea cucumber dermis is a key source for developing adaptable materials.

Purpose of the Study:

• To review current knowledge on MCT's structural, physiological, and molecular adaptations.
• To explore the mechanisms behind MCT's variable tensile properties.
• To survey biomimetic systems inspired by MCT and propose future exploitation strategies.

Main Methods:

• Literature review of existing research on echinoderm mutable collagenous tissue.
• Analysis of structural, physiological, and molecular adaptations of MCT.
• Survey of biomimetic systems derived from MCT biology.

Main Results:

• MCT's mechanical properties (tensile strength, elastic stiffness) are rapidly adjustable via neural control.
• Biomimetic systems inspired by MCT include both bio-derived and technology-derived approaches.
• MCT serves as a significant source of inspiration for novel mechanically adaptable materials.

Conclusions:

• MCT is a promising biological resource for developing advanced materials.
• Understanding MCT's mechanisms can drive innovation in biomedical science, chemical engineering, and robotics.
• Further exploitation of MCT can lead to new biomimetic technologies.
