Plain English summary

The paper reviews soft skins that can change thickness to create different shapes and interactions without needing rigid supports. These materials can deform in ways that allow for new types of touch and movement, making them useful in robotics and other applications.

Why this matters

This research addresses the need for more adaptable materials in robotics, which can enhance how machines interact with their environments. By improving the design and functionality of soft skins, this work could lead to more advanced and capable robotic systems.

Key findings

  • Thickness morphing enables new modes of haptic interaction.
  • The review covers various actuation stimuli and material platforms.
  • Emphasis on hierarchical elastomer composites and origami-inspired designs.
  • Challenges include durability, energy efficiency, and scalable manufacturing.
  • Potential for self-powered and intelligent soft skins.

What's new

The paper presents thickness modulation as a strategic design approach rather than just an actuation outcome.

Limitations

Key challenges in durability, energy efficiency, and integration of systems are acknowledged but not fully addressed.

Commercial context

The abstract does not provide information on commercial availability or readiness.
