Fig. 6

a The flight trajectories of 40 m free-falling motion patterns of the saddle and hemisphere microfliers as observed in recorded test movies. b The landing positions and final states of the microfliers after dispersion in warm/cold areas and four typical environments (forest, brushwood, hill, and road). c The short-term monitoring data of different environmental parameters obtained by microfliers in 4 typical scenarios of (b). Variations of environmental parameters are measured in every 2 min. d, e Temperature and pressure readings from a 7-day outdoor deployed microflier.
