Monolithic Biohybrid Flexure Mechanism Actuated by Bioengineered Skeletal Muscle Tissue

open access: yesAdvanced Intelligent Systems, EarlyView.
A scalable, monolithic biohybrid flexure mechanism is presented, integrating engineered skeletal muscle tissue with a soft, biocompatible, hollow silicone cylinder featuring dual pillars. Muscle contraction induces bending motion upon electrical stimulation, with performance governed by the structure's flexural rigidity.

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 ...

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.
