“…Additionally, the wall thickness of the hind wing veins on the dorsal side was thicker than that on the ventral side. This was also found in the Asian ladybeetle (Harmonia Axyridis) [41]. Thicker wing veins are good for sustaining greater forces and preventing the hind wings from being damaged [42].…”

When beetles are not in flight, their hind wings are folded and hidden under the elytra to reduce their size. This provided inspiration for the design of flapping-wing micro aerial vehicles (FWMAVs). In this paper, microstructures and nanomechanical properties of three beetle species with different wing folding ratios living in different environments were investigated. Factors affecting their flight performance, that is, wind speed, folding ratio, aspect ratio, and flapping frequency, were examined using a wind tunnel. It was found that the wing folding ratio correlated with the lift force of the beetles. Wind speed, folding ratio, aspect ratio, and flapping frequency had a combined effect on the flight performance of the beetles. The results will be helpful to design new deployable FWMAVs.

Background: The surface condition of mechanical parts has an important impact on the performance of the machine. Surface microtexture technology based on bionics is an effective method to improve the comprehensive performance of the surface of machine parts. Processing microscopic pits, convex-hull, microgrooves, and scale texture on the surface of parts can reduce wear, increase friction, improve lubrication performance, enhance hydrophobic properties, decrease drag and reduce noise. Surface microtexture technology has been widely used in many types of machinery, embodying various properties in working situation. Objective: The objective of this study was to provide an overview of recent patents and related research on surface microtexture technology, and to provide a reference for further applications. Methods: This paper introduces the development of surface microtexture technology, reviews the representative patents on surface microtexture and their applications in industrial products, including cutting tools, bearings, gears, blades, etc. The advantages and disadvantages of various surface microtextures are analyzed. Results: Through the analysis and comparison of surface microtextures, the influence of surface microtexture on friction and wear, lubrication and sealing, reduction of drag and noise, and hydrophobicity is summarized. The main problems and future development of surface microtexture technology are discussed. Conclusion: Different shapes of microtexture have different functions. The geometrical parameters of microtexture have a great influence on the surface properties. Therefore, the surface performance can be improved by designing the shape of the microtexture and optimizing the geometric parameters. In the future, more patents for surface microtexture will be invented and applied.
