Smart flapping wings with a PVDF sensor to modify aerodynamic performance of a micro UAV [PDF]
, 2007 This paper describes a new configuration of flapping wings to study the aerodynamic behavior of a microUAV (unmanned aerial vehicle). The flapping wings are composed of a pure parylene right wing and a PVDF-parylene composite left wing on purpose.

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.

Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures
Small, EarlyView.Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).

Wildlife Biology, EarlyView.Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Wind, waves, wing loading and the flight energetics of giant petrels
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Wind is a major factor driving seabird movement and energetics, the effects of which are modulated by morphology. Developments in tagging technology now make it possible to test predictions from aerodynamic theory about the effects of wind on flight performance in free ...
