Nature manufactures structures via decentralized processes involving groups of agents. This is fundamentally different from traditional manufacturing, where objects are produced sequences predefined steps. In this work, we explore the idea using simulated “swarms” simple agents to generate new designs for architected materials in a decentralized, bioinspired manner. Individual choose their own actions based solely on information immediate environment, with no centralized control. The that these produce result collective action individual agents, rather than predetermined design. We build an integrated platform determining “rule-structure-property” relationships, analogous process-structure-property relationships science. simulates agent behaviors show how rules and environments structures. then three-dimensional print perform finite element analysis experimentally numerically characterize mechanical properties, including tensile strength energy dissipation.

Architected flexible electronic devices with rationally designed 3D geometries have found essential applications in biology, medicine, therapeutics, sensing/imaging, energy, robotics, and daily healthcare. Mechanically-guided assembly methods, exploiting mechanics principles of materials structures to transform planar fabricated using mature semiconductor techniques into architected ones, are promising routes such devices. Here, we comprehensively review mechanically-guided methods for electronics. Mainstream classified discussed on the basis their fundamental deformation modes (i.e., rolling, folding, curving, buckling). Diverse interconnects device forms then summarized, which correspond two key components an device. Afterward, structure-induced functionalities highlighted provide guidelines function-driven structural designs electronics, followed by a collective summary resulting applications. Finally, conclusions outlooks given, covering achieve extreme deformations dimensions, inverse design encapsulation strategies as well perspectives future

Underwater devices are critical for environmental applications. However, existing prototypes typically use bulky, noisy actuators and limited configurations. Consequently, they struggle to ensure noise-free gentle interactions with underwater species when realizing practical functions. Therefore, we developed a jellyfish-like robotic platform enabled by synergy of electrohydraulic hybrid structure rigid soft components. Our 16-cm-diameter prototype could control the fluid flow propel while manipulating objects be kept beneath its body without physical contact, thereby enabling safer interactions. Its against-gravity speed was up 6.1 cm/s, substantially quicker than other examples in literature, only requiring low input power around 100 mW. Moreover, using platform, demonstrated contact-based object manipulation, fluidic mixing, shape adaptation, steering, wireless swimming, cooperation two three robots. This study introduces versatile wide range functions diverse

With the rapid development of micro/nanofabrication technologies, concept transformable kirigami has been applied for device fabrication in microscopic world. However, most nano-kirigami structures and devices were typically fabricated or transformed at fixed positions restricted to limited mechanical motion along a single axis due their small sizes, which significantly limits functionalities applications. Here, we demonstrate precise shaping position control microrotors. Metallic microrotors with size ~10 micrometers deliberately released from substrates readily manipulated through multimode actuation controllable speed direction using an advanced optoelectronic tweezers technique. The underlying mechanisms versatile interactions between electric field are uncovered by theoretical modeling systematic analysis. This work reports novel methodology fabricate manipulate micro/nanorotors well-designed sophisticated morphologies, providing new solutions future micro/nanomachinery.
