Core Viewpoint - The article discusses the development of a new hybrid adhesion suction disc inspired by the lamprey, which overcomes challenges in amphibious environments and rough surfaces, enhancing the adaptability of robots in various conditions [2][5][10]. Group 1: Scientific Problem - The research addresses how negative pressure adhesion and mechanical locking can work together to overcome the limitations of adhesion on rough surfaces, aiming for stable and reversible universal adhesion [7]. - The study reveals the synergistic mechanism of "negative pressure adhesion + mechanical locking," inspired by the lamprey's mouth structure, and is published in the journal "Cyborg and Bionic Systems" [7]. Group 2: Performance Validation - The hybrid suction disc achieves a maximum adhesion force of 562.6 N in air and 590.7 N underwater, allowing it to lift objects over 850 times its own weight of 70 g [13]. - The introduction of the SMP layer enhances adhesion strength by 377% in air and 270% underwater compared to traditional suction methods, maintaining adhesion even on rough surfaces with a roughness of Ra 707 µm [13]. - The suction disc can maintain adhesion for up to 26.8 hours under a 5N load in air, a 195% improvement over the control group without SMP, and shows a 540% increase in underwater environments [13]. Group 3: Application Demonstration - The suction disc demonstrates versatility by successfully gripping objects across a wide weight range, from 0.01 g electronic chips to an 11.4 kg wooden tabletop, and adapts to various surface geometries [16][17]. - In underwater environments, the suction disc maintains stable adhesion on both smooth and complex surfaces, showcasing its adaptability [17]. - A notable demonstration involved the suction disc integrated with a robotic arm, successfully transitioning between air and water while maintaining reliable adhesion [18].

Core Viewpoint - A breakthrough research team from KAIST has developed a novel bidirectional shape memory alloy/polymer composite material (SMA/SMPC) actuator, achieving significant performance improvements in the field of materials science [1]. Group 1: Performance Metrics - The new actuator demonstrates a reversible recovery rate of 82% and a reversible deformation range of 140° (88.7 mm), significantly surpassing existing technologies [2][17]. - Traditional shape memory materials are limited to unidirectional irreversible deformation, requiring reprogramming after each use, which restricts their application in repetitive task scenarios [5]. Group 2: Material and Structural Innovations - The research team employed dual strategies of material modification and structural optimization to address the limitations of traditional materials. They adjusted the stoichiometric ratio of DGEBA and DDM in the epoxy resin matrix to control the glass transition temperature of the shape memory polymer and introduced continuous carbon fiber reinforcement to enhance the composite's elastic modulus [6]. - An innovative "tape-spring" structure design was introduced, which utilizes transverse curvature to create a snap-through effect, significantly enhancing actuator performance [7]. Group 3: Simulation and Experimental Validation - Finite element simulation results indicate that the tape-spring structure exhibits higher effective bending stiffness in the initial bending phase compared to traditional flat structures, leading to a dramatic decrease in required bending moment during deformation [8]. - Experimental data confirmed that the TS_20 actuator, designed with the tape-spring structure, achieved a forward recovery speed 7.8 times faster than flat structures and a 30% increase in reverse recovery speed, with nearly 100% reverse recovery rate during thermal cycling [9]. Group 4: Application Potential and Durability - The actuator's practical applications were demonstrated in two scenarios: robotic grippers, where it can complete a grasping action in one second, and aerospace deployable structures, which can maintain a compact state at low temperatures and expand with a simple heating-cooling cycle [15]. - Durability tests showed that the actuator maintained stable shape memory performance over 10 thermal cycles, with an average forward recovery rate of 80% and a reverse recovery rate exceeding 99%, confirming its reliability [17].
