Research on “Insect scale flapping robot flying by electromagnetic radio transmission” by Takashi Ozaki et.al., was published in Nature Electronics.
Ultra-lightweight aerial vehicles are useful tools for communication devices, environmental sensing, and surveying in disaster areas. However, the lack of lightweight high-power-density batteries has limited the untethered flight durations of these micro aerial vehicles. In this study, we have developed an insect-scale flapping-wing aerial vehicle that can fly without batteries by wireless power transmission using radiofrequency electromagnetic waves. The total weight of our vehicle is only 1.8g; this is currently the world's lightest RF-powered aircraft, more than 25 times lighter than previous models.
The image of this robot is used on the cover of the November issue of Nature Electronics.
