See The World’s Smallest Drone – A Cyborg Dragonfly
” The smaller a drone gets, the more places it can be easily flown. But while many researchers have been trying to tackle the monumental challenge of building drones that look and behave like tiny insects, a new approach has engineers giving Mother Nature’s existing creations drone-like upgrades.
The biggest hurdle with building tiny drones that can fly almost anywhere is powering them. A small flying craft is only strong enough to carry a small battery, which dramatically limits its flight time. But somehow that mosquito in your tent while camping can buzz your ear for hours on end before refueling—on you.”
” We can only make electronics so small, though, so upgrading a mosquito isn’t currently feasible. But a dragonfly? Researchers at Charles Stark Draper Laboratory and Howard Hughes Medical Institute have created something they call DragonflEye: a remote control drone built on a living dragonfly.”
