Hypothesis

The study investigates the capillary forces and capillary rise in a three-finger microgripper and a plate.

Conclusion

The experimental results verify the validity of the capillary bridge model and the capillary force theory solution method.

Supporting Evidence

  • The maximum capillary forces from the model and experiments were 95.2 μN and 96.0 μN, respectively.
  • The study established a capillary bridge model using the energy minimization method.
  • The influences of separation distance, capillary bridge volume, and radial distance on capillary force were investigated.

Takeaway

This study looks at how a special tool with three fingers can pick up tiny objects using water's surface tension.

Methodology

The study used numerical simulations and experimental validation to measure capillary forces at different conditions.

Limitations

The study does not address the effects of environmental factors on capillary forces.
