How Does a Delicate Insect Wing Resist Damage? Chitin Orientation Is Adapted to the Mechanical Demands at the Nanoscale

Advanced Materials, Volume 37, Issue 51, December 23, 2025.
Nanoscale chitin fiber orientations in the insect wing play a critical role in adapting to complex mechanical demands. These findings reveal two distinct and functionally adaptive chitin orientation patterns in the membranes that vary regionally, optimizing mechanical resilience and deformation control.

Toward a Dielectric Elastomer Resonator Driven Flapping Wing Micro Air Vehicle

Frontiers in Robotics and AI, 2019
In the last two decades, insect-inspired flapping wing micro air vehicles (MAVs) have attracted great attention for their potential for highly agile flight. Insects flap their wings at the resonant frequencies of their flapping mechanisms.

Flapping Wing Micro Air Vehicle

, 2018
Background:   Vibrational stability is a natural phenomenon where a system if vibrating at sufficiently high frequencies, can bring itself back into a stable state if perturbed. This is akin to the high frequency flapping that hummingbirds and insects employ to maintain a hovering position and fly. Micro Air Vehicles (MAV) are a subset of air

Flight Altitude of Common Cranes (Grus grus) Crossing the Arkona Basin (Baltic Sea): Implications for Offshore Wind Farm Development

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Study comprises the first field study of the flight altitude of the common crane (Grus grus) during seasonal migrations across the Baltic Sea. Our investigations clearly indicate that despite weather‐induced variations in the flight altitude, the majority of cranes will cross the Baltic Sea at altitudes between 50 and 250 m.

The birds and the trees: Avian ecosystem (dis)service perspectives and farmers' willingness to plant native trees in the agricultural landscape of the Galapagos Islands

People and Nature, Volume 7, Issue 12, Page 3182-3206, December 2025.
Abstract Agricultural landscapes hold great potential for biodiversity conservation; however, this will require finding solutions that work for both people and nature. Increasingly, the conservation community is calling for more cross‐disciplinary research integrating ecological questions with social and behavioural sciences for a more complete and ...

Identification of Fixed-Wing Micro Aerial Vehicle Aerodynamic Derivatives from Dynamic Water Tunnel Tests

Aerospace, 2020
A micro air vehicle (MAV) is a class of miniature unmanned aerial vehicles that has a size restriction and may be autonomous. Fixed-wing MAVs are very attractive for outdoor surveillance missions since they generally offer better payload and endurance ...

Design and Construction of an Experiment for the Investigation of the Effects of Gust on Flapping Wing Micro Air Vehicle Power Consumption [PDF]

, 2013
In recent years, the promising nature of flapping wing flight has led researchers to investigate the wing morphology and unsteady wing aerodynamics found in insects to aid in the design of modern micro air vehicles (MAVs).
