摘要

We report the electrostatic levitation of various kinds of seeds and flower buds.Coral berry and pepper near a spherical shape show a stable levitation state.The prolate ellipsoid soybeau and flower buds are always “standing” in the free space with satisfactory levitation stabiiity.For the irregular mushroom and wheat grain,the levitation state is characterized as a “top-heavy” posture.These special stable equilibrium states are proved by the analysis of surface charge distribution.The obtained saturation polarization charge of samples presents a good accordance with experimental data.The levitation ability is weighed by thefactor m(εr + 2) / (εrD2 ).
