Aerial Sowing
Background
This case showcases a device inspired by winged seeds for efficient seed dispersal. At low temperatures, the winged structure naturally spins, extending its descent time and spreading seeds over a larger area. The origami release structure expands only in high humidity, ensuring precise seed drop and optimal timing for distribution. When released from a height, the spinning seeds can travel much further than non-rotating ones, demonstrating superior dispersal efficiency.
How it Works
- Under moderate temperatures, the winged seeds (dispersal structure) naturally curve, causing them to spin as they descend. This spinning motion extends their fall time, allowing seeds to be dispersed over a wider area.
- The origami structure (release structure) opens only when humidity increases, allowing the seeds to be released at the right moment.
Coordinating Mode
The device design follows the Synergistic Mode.
Result
We tested the device by releasing winged seeds from a height of 1.6 meters. With a wind speed of 1.2 m/s, the maximum linear dispersal distance reached 2.1 meters, significantly farther than non-spinning seeds (0.3 meters).
