Extended Data Fig. 4: 3D microflier with porous design.
From: Three-dimensional electronic microfliers inspired by wind-dispersed seeds
(a) Inspiration of porosity from nature: optical images of dandelion seeds and a feather. (b) FE simulated configuration of a 3D void-free microflier (p = 0) and a 3D microflier of porosity design (p = 0.26). (c) Images of scanned thickness of a 2D precursor for a porous microflier, with top view and perspective view, respectively. (d) G0(b) and (e) G1(b) versus the attack angle for various porosities. Normalized (f) G0(b) and (g) G1(b) over their void-free values versus porosity, with the CFD values of various \(\alpha \in [0^\circ ,90^\circ ]\) and analytic fittings.
