  • Microassembly requires the precise and reliable stacking of microcomponents. Robotic tools are usually used, but recent studies have found that combining robotics with self-assembly can improve performance by increasing speed and accuracy simultaneously.

    One possibility is to use the surface tension of a liquid droplet for aligning two components with each other. In this study, droplet self-alignment is modeled to reveal alignment force and accuracy in multiple microassembly scenarios.
