Spring and Power in Hovering Ornithopters

open access: yesAdvanced Intelligent Systems, EarlyView.
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 ...

A Motion‐Sensing Integrated Soft Robot with Triboelectric Nanogenerator for Pipeline Inspection

open access: yesAdvanced Intelligent Systems, EarlyView.
A soft robot integrated with triboelectric nanogenerator‐based tactile sensors is proposed to achieve locomotion within pipelines and exteroception of different materials and structures of pipeline inner surfaces. By introducing a 1D‐convolutional neural network algorithm, the soft robot's accuracy in recognizing eight different pipe inner surface ...

Anchor Peptide‐Based Immobilization Strategy Promote the Applications of Pickering Emulsion System in Natural Products Glycosylation

open access: yesAngewandte Chemie, EarlyView.
This study designs an anchor peptide‐based immobilization strategy to expand the application of Pickering emulsion to glycosyltransferases (GTs) for the first time, addressing low conversion challenge in aqueous solutions. The glycosylation Pickering emulsion achieved more than 90% conversion of natural product glycosides with high recyclability ...
