Tiny Solar-Powered Devices Fly in the Wind Like Dandelion Seeds

A dandelion-inspired sensor.

Inspired by how dandelions use the wind to distribute their seeds, a University of Washington team has developed a tiny sensor-carrying device that can be blown by the wind as it tumbles toward the ground. This battery-free device uses solar panels (black rectangles shown here) to power its onboard electronics. (Image: Mark Stone via University of Washington)
