Fluid Reconfigurable Intelligent Surfaces: Joint On-Off Selection and Beamforming with Discrete Phase Shifts [PDF]
This letter proposes a fluid reconfigurable intelligent surface (FRIS) paradigm, extending the conventional reconfigurable intelligent surface (RIS) technology to incorporate position reconfigurability of the elements. In our model, a `fluid' element is realized by a dense matrix of subelements over a given space and dynamically selecting specific ...

ABSTRACT Typically, batteries are the main power source for mobile robots, and the practical constraints in carrying them pose challenges in achieving efficiency, autonomy, and safety objectives in robotic missions. Moreover, dealing with battery degradation requires a precise understanding of energy consumers' behavior in the system.

Complex Assemblies of Colloidal Microparticles with Compliant DNA Linkers and Magnetic Actuation
High‐surface‐energy polycarbonate templates are used to assemble polystyrene microspheres, improving yields more than 100‐fold. These higher yields facilitate the construction of active colloids and complex microstructures, including 10‐sphere microrotors and a 26‐sphere “CMU.” These active colloids are connected with compliant DNA linkages, enabling ...
