Area of Science:

  • Materials Science
  • Mechanics
  • Biomedical Engineering

Background:

  • Conventional mechanoresponsive materials struggle to detect low-level compression stresses (kPa range) due to insufficient molecular motion.
  • Imaging stress distribution, especially at low stress levels, remains a significant challenge in various scientific and medical fields.

Purpose of the Study:

  • To develop a novel device for the sensitive detection, imaging, and measurement of weak compression stresses.
  • To overcome the limitations of existing mechanoresponsive materials in detecting and visualizing low-magnitude stresses.
  • To demonstrate the device's utility in clinical settings, specifically in surgical operations.

Main Methods:

  • A sponge device was engineered by integrating stimuli-responsive capsules with polydiacetylene (PDA)-coated melamine sponge fibers.
  • Compression stress triggers capsule collapse and liquid release, initiating an irreversible color change in the PDA.
  • The cascading response allows for colorimetric imaging and quantification of stress distribution.

Main Results:

  • The device successfully images and measures compression stresses in the kPa range, previously undetectable by conventional methods.
  • It enables the visualization of stress distribution from irregular-shaped objects.
  • The device was applied to analyze stress in simulated clinical scenarios involving intestinal surgery.

Conclusions:

  • The developed sponge device offers a robust platform for colorimetric stress imaging and measurement at low stress levels.
  • This technology has broad applicability in fields requiring sensitive stress detection, including biomedical engineering and materials science.
  • The design strategy provides a foundation for future advancements in stimuli-responsive materials for stress analysis.
