Magnetic Fluid‐Driven Vine Robots for Minimally Invasive Tissue Biopsy Sampling

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a magnetic fluid‐powered vine robot for minimally invasive biopsies. The robot uses fluid pressurization for locomotion and external magnetic fields for precise steering. Its soft structure and high magnetic volume ensure controlled movements and stabilization, enabling effective tissue penetration.

Treecreeper Drone: Adaptive Mechanism for Passive Tree Trunk Perching

open access: yesAdvanced Intelligent Systems, EarlyView.
Taking inspiration from treecreepers, a passively triggered aerial robot that can reliably perch on vertical tree trunks is presented. The friction‐based approach combines a microspine array with a tail‐like support, and then validates via dynamic analyses and flight experiments, ensuring stable performance across trunk diameters and bark textures ...

Poligromorph Materials: Shape Morphing Functional Polyvinyl Alcohol/Maleic Anhydride Ethylene‐Propylene/Carbon Composites in Aqueous and Hydrocarbon‐Based Media

open access: yesAdvanced Intelligent Systems, EarlyView.
Hygromorphic materials, such as pinecone scales, respond to humidity changes. This study presents poligromorphic composites—composed of carbon fibers (CFs), polyvinyl alcohol (PVA), and maleic anhydride ethylene‐propylene (MA‐EPR)—that react to water, humidity, and hydrocarbons.
