However, the use of a thick electrolyte layer (>40 nm) in conventional ECRAMs leads to an unavoidable tradeoff between synaptic weight updates and operating speed. To address this problem, a Cu-based ultrathin ECRAM (UT-ECRAM) that uses a single 5 nm HfOx active layer and a ≈1.2 nm AlOx liner is designed. The highly efficient gate-tunable fast Cu-ion transport in the AlOx/HfOx UT-ECRAM enables 1) near-ideal linearity in weight updates (0.45) even achieved with a pulse width (tw) of 50 μs, 2) dynamic multilevel retention of 104 s, and 3) reliable cycling endurance of 104 cycles. A numerical analysis based on device scaling quantitatively reveals that a relatively high concentration of field-driven Cu ions (≈1020 cm−3) contributes to each synaptic weight update per gate voltage (VG) pulse in the UT-ECRAM without becoming deactivated by traversing thicker layers. This improved gate sensitivity can ultimately overcome the linearity and the ratio/speed tradeoff relationships, paving the way for robust neuromorphic synaptic units.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202500416","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, a comprehensive framework is introduced for the design and control of modular soft robotic devices. These modules can be combined in various configurations to develop a wide range of haptic devices capable of dynamically modifying their stiffness and shape to accommodate different applications, including providing haptic feedback in virtual environments and assisting individuals with hand rehabilitation needs. The design methodology of these modules is reported and two potential use cases are presented.

Amphibious robots address this need by operating in both aquatic and terrestrial settings, leveraging biomimetic designs and integrated mechanical propulsion systems. While these robots has traditionally drawn inspiration from reptiles, crustaceans, and amphibians, there has been comparatively less exploration of swimming-capable mammals and birds as biological models. In this work, DuckyDog, a quadruped amphibious robot using erect posture has been proposed and developed to take full advantage of the high mobility of mammals on land. By integrating a duck-like body and passive fins, it also has excellent swimming ability on the water surface. Whereas many robots rely on soft materials to construct compliant legs, DuckyDog is distinguished by its fused deposition modeling-printed legs made from polylactic acid (PLA) filament, featuring structurally induced variable stiffness and actuated through a tendon-driven mechanism. A series of experiments are conducted to evaluate DuckyDog's terrestrial and aquatic locomotion performance in both laboratory settings and complex natural environments, where it achieves maximum speeds of 0.40 body lengths per second on land and 0.30 in water.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 7","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202500267","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cardiac assist devices are crucial treatment modalities for end-stage HF, but they still face limitations, such as direct blood contact and high power consumption. We present a lightweight (<60 g), compact, electroactive polymer (EAP)-based cardiac assist device (E-CAD) as a nonblood-contacting, low-power alternative to address these limitations. E-CAD consists of EAP units paired with negative bias springs (NBSs), mounted on a flexible sleeve that wraps around the heart to assist in cardiac compression. The device is designed to be biomimetic to match the regionally varying mechanical stiffness of the heart. Benchtop silicone phantom and ex vivo porcine tests demonstrated E-CAD's ability to increase volume displacement by 1.21-fold in benchtop tests with a silicone phantom and 1.17-fold in ex vivo settings, along with an associated increase in ejection fraction, compared to cases without the device. Furthermore, it operates on low power (<0.3 W), enabling a compact design with a thin driveline (outer diameter = 0.3 mm), which reduces infection risk. In summary, we showed that EAP-based direct cardiac compression was feasible with low power demand. The improvement in cardiac output may translate into clinical benefits for advanced HF patients.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202500076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of zinc ferrite further allows for grafting alkyne-bearing ligands on the nanoparticles, enabling them to be covalently immobilized within the hydrogel framework via azide-alkyne cycloaddition, thereby improving the composite's stability.

Perching on trees offers a promising solution by enabling prolonged observations with reduced energy consumption. To overcome perching location limitations, in this article, a bird-inspired passive perching mechanism specifically optimized for vertical tree trunks is proposed. Similar to the tail action of treecreepers (Certhiidae family) when perching on vertical tree trunks, the proposed aerial robotic platform perches on tree surfaces using a main clawed gripping mechanism combined with a supporting “tail” mechanism featuring arrays of embedded microspines. To cope with the complex curvature of tree trunks, adaptive elastic joints that allow the mechanism to passively contact the tree's surface are introduced. By incorporating the region of attraction for the mechanism, the aerial platform is designed to be more reliable during perching maneuvers by adjusting angular movement, thereby defining suitable initial velocities and accelerations for achieving stable equilibrium. The proposed system is validated in a motion capture environment using vertical trunks with diameters ranging from 40 to 220 mm, and further demonstrates in outdoor perching tests. Results confirm the feasibility of dynamic perching on vertical tree trunks under realistic forest conditions.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202401101","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many existing shape-morphing robots rely on the inherent softness of materials or structures, which sacrifices load-bearing capacity. Despite efforts to achieve both morphing and stiffness tuning in one system, these strategies often rely on separate mechanisms, such as heating liquid metal components to reduce rigidity before employing other mechanisms to change the shape, leading to bulky and complex systems that limit practicality and scalability. Here, a tunable-stiffness architected morphing structure (TSAMS) is introduced, which unifies shape morphing and tunable stiffness in a single, compact platform. By combining 3D-printed tessellated particles with shape memory alloy springs, TSAMS transitions smoothly from soft to rigid states, exhibiting a ≈308 times increase in bending stiffness while concurrently executing intricate shape transformations through electrothermal actuation. This design is demonstrated with the following robotic applications, including rolling robots that can explore diverse terrains by climbing slopes, avoiding obstacles, and carrying loads; compact manipulators that lift objects nearly 50 times heavier than themselves; and snake-inspired robots performing undulation and sidewinding gaits. These results highlight TSAMS's potential to advance next-generation soft robots and bioinspired systems that demand both dynamic shape reconfiguration and robust structural performance in diverse operating conditions.","PeriodicalId":93858,"journal":{"name":"Advanced intelligent systems (Weinheim an der Bergstrasse, Germany)","volume":"7 9","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/aisy.202500123","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike previous deep learning approaches that function as black boxes, this physics-informed framework prioritizes interpretability, providing a clearer understanding of light propagation through scattering media and enabling the estimation of the transmission matrix. A key advantage of this digital twin is its differentiable nature, allowing gradient-based optimization for solving inverse problems, such as retrieving the initial wavefront of light that passed through the medium. The results demonstrate superior accuracy compared to models directly optimized for this task, highlighting the precision and robustness of the proposed approach.
