Abstract Bioelectronics, which integrate biological systems with electronic components, have attracted significant attention in developing biomimetic materials and advanced hardware architectures to enable novel information‐processing systems, sensors, actuators. However, the rigidity of conjugated molecular lack reconfigurability static crosslinked structures pose challenges for flexible sensing applications. Topological networks (TCNs) featuring dynamic interactions offer enhanced flexibility environmentally induced reconfigurability, decoupling competition between performances. Here, recent advances are summarized assembly methods bioelectronics different TCNs elaborate ion/electron‐transport mechanisms from perspective interactions. Decoupling effects can be achieved by comparing distinct their respective properties, an outlook is provided on a new range neuromorphic biocompatibility, self‐healing, self‐powered, multimodal‐sensing capabilities. The development TCN‐based significantly impact fields artificial perception devices, networks, systems.

Hydraulically Amplified Rigidity-Adaptive Electrostatic Actuators with High Performance and Smooth Motion Control

Soft Robotics, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

Hydraulically amplified self-healing electrostatic (HASEL) actuators are known for their muscle-like activation, rapid operation, and direct electrical control, making them highly versatile use in soft robotics. While current methods enhancing HASEL actuator performance largely emphasize material innovation, our approach offers an additional architectural strategy. In this study, we introduce a novel hydraulically rigidity-adaptive (HARIE) designed to significantly enhance while maintaining controllability by elucidating the underlying issues of pull-in instability. Our experimental results indicate that HARIE achieves significant improvement, with over 200% increase angular output consistently strong torque compared flexible electrodes. Notably, maximum step is 21.8°/kV, approximately one third rigid electrodes (62.3°/kV), suggesting smoother motion control. The actuator's effectiveness further demonstrated practical applications; it successfully grasps orange weighing 15.2 g delicate dandelion. Additionally, precise targeting capability evidenced its ability manipulate laser induce heat accumulation, leading balloon's breakdown, thereby showcasing high level controllability. method mitigates negative impacts suboptimal materials demonstrates potential enhancement when combined superior materials.

Enhancing compliant gripper performance: Exploiting electro-adhesion to increase lifting force over grasping force

Robotics and Computer-Integrated Manufacturing, Journal Year: 2024, Volume and Issue: 91, P. 102843 - 102843

On the landscape of solutions to deal with delicate objects, development and use soft grippers is a topic increasing interest, large number prototypes proposed by research community employing non-linear materials based on diverse actuation means. However, compliance usually leads reduction lifting capacity. As recent promising approach, shear forces exerted gripper can be enhanced exploiting electro-adhesion (EA) effect. Following this trend, paper proposes new that combines compliant finger structure, geometry taken from FESTO FinRay but made softer material (a urethane rubber), custom EA pads are placed fingers at interface grasped object. hyper-elastic model identification considered preliminary functional verification design via finite element simulations, then manufactured tested means specific setup, replicating grasping cylindrical objects different diameters. The results clearly show makes it possible generate holding similar those FinRay, significantly lower pressures object (77 % less). Besides enabling handling more fragile items, drastic increase in also mechanical force (namely, 71 less gripping energy) required same force, consequent operation costs sustainability its application.
