Topography‐Free Dual‐Lubricant Patterned Slippery Surfaces for Programmable Droplet Control and High‐Performance Water Harvesting

Small, EarlyView.
A patterned dual‐lubricant SLIPS creates interfacial energy asymmetry, guiding droplet migration without external actuation. Condensed droplets formed on the fluorinated‐oil‐infused regions migrate to the silicone‐oil‐infused domains, where rapid growth and coalescence occur.

Multi‐Material Droplet‐Based Hydrogel Threads for Extrusion 3D Printing

Small Methods, EarlyView.
This study introduces a novel approach to produce multi‐material threads for 3D printing by precisely arranging hydrogel droplets separated by lipid bilayers. By merging the precision of inkjet printing with the scalability of extrusion printing, this method prevents cross‐contamination, maintains material control, and enables intricate designs ...

Direct drive or slider-crank? Comparing motor-actuated flapping-wing micro aerial vehicles

Drone Systems and Applications
For flapping-wing micro aerial vehicles, the common approach to converting the rotational motion of a DC motor to the reciprocal flapping motion is using a slider-crank mechanism. However, frictional losses in sliders and rotational joints can hinder the

Delta Parallel Robot Based on Crank-Slider Mechanism

IEEE International Conference on Robotics and Automation, 2017
A three-degree-of-freedom Delta parallel manipulator driven by a crank-slider mechanism is proposed. In Cartesian space, a gate-shaped curve is taken as the path of the pick-and-place operation, combining with the inverse kinematics theory of the Delta ...
