Flying Like an Insect: How Strain Sensors are Transforming Drone Flight
This breakthrough could be vital in advancing drone technology for applications like search-and-rescue missions, environmental monitoring, or even delivery services in challenging weather conditions.

The ability of insects to gracefully navigate complex, windy environments has long fascinated scientists. Tiny creatures like dragonflies can hover, turn sharply, and adjust their flight in response to subtle changes in the air. Replicating these abilities in drones could open the door to more efficient, agile flying machines. But doing so is a huge challenge—until now.
A team of researchers has taken a significant step toward this goal by designing a new flight control system for flapping-wing drones that mimics the way insects sense their environment. Their system uses wing strain sensors, inspired by the mechanoreceptors found in insect wings. These sensors detect tiny changes in the wings as they interact with the wind, giving the drone critical information about its surroundings.
