Spring and Power in Hovering Ornithopters
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Woven, In‐Air, Textile Actuators by Conjugated Polymers and Solid‐State Electrolyte Tape Yarns
Herein, the concept of fabric actuators with trilayer tape yarns is reported. The tape yarns consist of conjugated polymer layers and ionogel, as an ion reservoir, enabling actuation in‐air. Using textile techniques to create actuators offer many advantages, such as parallel assembly for increased force output, conductive yarns for electrical control ...

Toward Autonomous Self‐Healing in Soft Robotics: A Review and Perspective for Future Research
In this article, five different phases (damage detection, cleaning, damage closure, material healing, and healing assessment) are investigated to have an autonomous self‐healing at the system level with the focus on soft robotics. It delves into the importance of each phase, why and where they matter, and reviews relevant technologies that enable ...

Design, Modeling, and Control of a Soft Robotic Diaphragm‐Assist Device in a Respiratory Simulator
A soft robotic diaphragm‐assist device using fabric‐based pneumatic actuators with a 2‐step control system to optimize synchronization and support is introduced. This system can detect the initiation of breathing to trigger assistance and regulate pressures to provide the correct level of inhalation augmentation. Validation and testing are completed on
