Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and ...

Bio-inspired wind sensing using strain sensors on flexible wings could revolutionize robotic flight control strategy. Researchers at Institute of Science Tokyo have developed a method to detect wind ...

Insects are thought to use specific chest muscles to actively open and close their wings. However, high-speed imaging reveals that rhinoceros beetles flap their hindwings to deploy them for flight, ...

Moving air with spinning blades is the most popular way, but it is not the only way. Using the PCB actuator technology he has been working on for the past few years, [Carl Bugeja] built a small ...
