Mitochondrial μ-cilia for climbing robots

Artificial version could help to propel tiny biomedical robots


Key points from article :

The artificial cilia that can beat just like the real thing.

They rely on magnetic fields to generate movement.

Movement of tiny soft robots in a variety of ways to ‘walk’ up vertical surfaces.

Soft robots have enormous biomedical potential.

Manipulating small devices is challenging, requiring some ingenuity.

The researchers incorporated carbonyl iron powder particles into a polymer mixture.

They used this to create small cilia-like projections by pouring the polymer into a mold.

They used rotating magnets to create a magnetic field around the resulting soft robot.

Which stimulated the cilia to move in a traveling wave because of the slightly different magnetic properties in adjacent cilia.

This technology could also be useful to propel very small amounts of water through microfluidic systems.
