Area of Science:

  • Robotics and Materials Science

Background:

  • Small-scale robots (SSRs) are vital for micro-scale applications but face motion challenges due to dominant viscous and surface forces.
  • Adhesive forces and surface tension significantly impede the efficiency and control of miniaturized robots.

Purpose of the Study:

  • To review the progress and future of SSRs modified with hydrophilic and hydrophobic surfaces.
  • To highlight how surface engineering addresses motion resistance and enhances SSR capabilities.

Main Methods:

  • Focuses on a review of existing literature on surface-engineered SSRs.
  • Examines both tethered and untethered SSRs with hydrophilic and hydrophobic functionalization.

Main Results:

  • Hydrophilic and hydrophobic surface modifications offer a novel strategy to overcome motion resistance in SSRs.
  • These modifications improve maneuverability, reduce drag forces, and enhance targeting capabilities.

Conclusions:

  • Rational surface engineering is key to unlocking the full potential of SSRs.
  • Advanced surface modifications promise enhanced mobility, functionality, deeper penetration, reduced fouling, and inhibited bacterial adhesion for SSRs.
