Light‐Driven, Dynamic Assembly of Micron‐To‐Centimeter Parts, Micromachines and Microbot Swarms
This work describes light‐driven assembly of dynamic formations and functional particle swarms controlled by appropriately programmed light patterns. The system capitalizes on the use of a fluidic bed whose low thermal conductivity assures that light‐generated heat remains “localized” and sets strong convective flows in the immediate vicinity of the particles being irradiated. In this way, even low‐power laser light or light from a desktop slide projector can be used to organize dynamic formations of objects spanning four orders of magnitude in size (from microns to centimeters) and over nine orders of magnitude in terms of mass. These dynamic assemblies include open‐lattice structures with individual particles performing intricate translational and/or rotational motions, density‐gradient particle arrays, nested architectures of mechanical components (e.g., planetary gears), or swarms of light‐actuated microbots controlling assembly of other objects.
