Human camouflage and expression via soft mask from reprogrammable chemical fluid skin

Science Advances, Journal Year: 2025, Volume and Issue: 11(7)

Published: Feb. 12, 2025

Developing a wearable, active, dynamic face-changing mask for human camouflage and expression is substantial challenge. Many organisms achieve through skin deformation color change. Inspired by this, we report reprogrammable chemical fluid skin, which achieves fluids like the of pufferfish change function chameleon. Based on design soft that allows switching between at least eight faces time. The lightweight, thin, fits wearer’s head. Its actuation silent safe, can realize facial switching, including shape. By wearing mask, robots show changes modulation, humans their as needed. Our work enables implementation transforming into other in real world to expression, which, date, exists only people’s imagination.

Accessing pluripotent drones through reprogramming of dynamic soft self-healing chemical growth

National Science Review, Journal Year: 2025, Volume and Issue: 12(6)

Published: Feb. 17, 2025

ABSTRACT The functions of drones that are implemented by existing design paradigms usually fixed and do not have the possibility further ‘differentiation’. Inspired biological concept pluripotency, here we report a pluripotent drone can ‘differentiate’ into series with different to perform variety challenging tasks. To realize this concept, propose method reprogrammable dynamic soft self-healing chemical growth (R-growth), which grow specific ‘organs’ achieve corresponding functions, after completing tasks, these be retracted. Furthermore, able respond possible damage through rapid (∼3.2 s, >1000 times faster than similar membranes). R-growth is large-scale (>1.5 m), fast (0.15 m/s), lightweight (∼5 g, 1/20 weight traditional micro air pumps), self-contained free-wheeling. This applied various significantly extend their enable an unprecedented range work realizes growth, retraction, switching any function, while such ability macro robots or humans, date, only exists in science fiction movies.

Hierarchically Reconfigurable Soft Robots with Reprogrammable Multimodal Actuation

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 18, 2024

Abstract Reconfigurable soft robots exhibit superior flexibility and adaptability when coping with complex environments variable tasks. However, conventional modular design strategy based on actuator modules specific structure actuation mode as the basic constructing element for reconfigurable always has limited reprogrammability or scalability. Here, a hierarchical is reported that not only offers module reconfiguration first level to build different robot prototypes, but also provides elastically‐guided multimodal (contraction, bend, twist) second which can be reprogrammed construct modules. This deepens modularity higher dimensionality more choices adjust various conformations functions needed, example, peristalsis robot, an omnidirectional crawling manipulator easily constructed using module‐level reconfiguration. Moreover, manipulators preprogrammed deformation trajectories are proven dramatically reduce operation difficulty cost in potential applications such environment detection human‐robot interaction. work framework may open up new way design.

Climbing robots have attracted growing attention due to their mobility on vertical and nonplanar structural surfaces. However, the development of climbing capable various complex surfaces remains elusive, especially discontinuous In nature, Parthenocissus climbs as it grows, having growing-climbing behaviors. Inspired by , we propose a mechanism report soft robot, which grows microstructured biofilms enhance adhesion, similar suckers adsorbing wall. The robot uses shape memory alloy contraction achieve bending, using gelatinous fibers hinge-like bending. addition, not damage site, can be fully contracted after completing tasks. climb surfaces, verifying effectiveness ’ mechanism. is universal paradigm, opening door for surface robots.

Embodying soft robots with octopus-inspired hierarchical suction intelligence

Science Robotics, Journal Year: 2025, Volume and Issue: 10(102)

Published: May 14, 2025

Octopuses exploit an efficient neuromuscular hierarchy to achieve complex dexterous body manipulation, integrating sensor-rich suckers, in-arm embodied computation, and centralized higher-level reasoning. Here, we take inspiration from the hierarchical intelligence of octopus demonstrate how, by exploiting fluidic energy information capacity simple suction cups, soft computational elements, actuators, can mimic key aspects structure in robotic systems. The presented works at two levels: By coupling flow with local circuitry, robots octopus-like low-level intelligence, including gently grasping delicate objects, adaptive curling, encapsulating objects unknown geometries, decoding pressure response a cup, multimodal high-level perception, contact detection, classification environmental medium surface roughness, prediction interactive pulling force. As octopuses, executes most its computation within lower-level circuitries, minimum is transmitted decision-making “brain.” This development provides insights into octopus-inspired machine through low-cost, simple, easy-to-integrate methods. be readily integrated fluidic-driven enhance their reduce requirement applied widely, industrial object handling manufacturing robot-assisted harvesting interventional health care.
