Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Robotics

Background:

  • Stimuli-responsive materials are crucial for soft robots in biomedical applications.
  • Current materials often use non-biodegradable polymers, limiting environmental compatibility.
  • There is a need for flexible, biodegradable, and magnetically responsive materials.

Purpose of the Study:

  • To develop a flexible, biodegradable, and magnetically sensitive cellulose film (M-film).
  • To utilize the M-film for creating magnetically controllable soft robots (M-robots).
  • To demonstrate M-robots' capabilities in programmable locomotion, cargo delivery, and wireless operation.

Main Methods:

  • Synthesized M-film using cellulose nanofibers, sodium alginate, and BaFe12O19 particles via a paper-making process.
  • Employed an origami-magnetization process to design M-robots with specific functionalities.
  • Investigated the M-film's magnetic, folding, and overall properties.

Main Results:

  • Successfully created a flexible, biodegradable, and magnetically sensitive cellulose film.
  • Developed M-robots capable of multimodal movements, including obstacle climbing.
  • Demonstrated cargo transport functions such as clawing, rolling, and flipping.
  • Showcased remote wireless operation capabilities.

Conclusions:

  • The developed M-film offers a biodegradable and magnetically responsive platform for soft robots.
  • This approach enhances the controllability and manipulability of cellulose nanomaterials.
  • Opens prospects for stimuli-responsive robots, wireless control electronics, and intelligent devices.
