UC Berkeley Creates World's Smallest Battery-Free Drone That Flies Using Magnetic Fields

UC Berkeley researchers have developed what they claim is the world’s smallest drone—a 21-milligram, battery-free device powered entirely by magnetic fields. The insect-scale flying robot is approximately one-third the weight of a honeybee and measures just 0.9 centimeters in diameter, making it more than three times smaller than any previous flying micro-robot, according to a recent report from Yanko Design. Innovative Magnetic Propulsion Syste…

UC Berkeley Unveils World’s Tiniest Battery-Free Drone Powered by Magnetic Fields - Yanko Design

Back when we imagined the future, flying robots were always loud, blinking, and somehow armed — straight out of a ‘90s sci-fi flick. The reality, as it turns out, is much quieter, more delicate, and surprisingly elegant. UC Berkeley’s latest creation, the world’s smallest battery-free flying robot, feels less like a Hollywood prop and more
