Faster engine for powering insect-sized robots

Spotted: Researchers at the University of Washington have developed a more efficient way to power miniature robots. The researchers use electrohydrodynamic (EHD) thrust, which requires no moving mechanical parts. EHD is similar to ion propulsion used in solar-powered spacecrafts.  Ion propulsion systems work by bombarding xenon atoms with electrons, which gives them a positive charge…
