The basic principle of electrostatic adsorption is realized by utilizing a capacitance system formed by a metal electrode and the surface of an absorbed object. The metal electrodes are arranged in a positive and negative staggered mode (but are not in contact) to form an electrostatic adsorption layer, and an electric field is formed between the positive electrode and the negative electrode and is divided into a main electric field and a fringe electric field. The main electric field line only passes through the inside of the electrostatic adsorption layer, while the fringe electric field passes through the space around the electrostatic adsorption layer and can cause the polarization of the surface of the absorbed object, so that the surface of the absorbed object collects the electric charges with the polarity opposite to that of the nearby electrode, and the collection of the electric charges can generate the electric field force between the object and the electrode of the electrostatic adsorption layer, thereby achieving the effect of attracting the object by the electrode.

The calculation formula of the adsorption force F is as follows: f = ε AV²/2d²ε is the dielectric constant of the fill between the electrodes, A is the plate area of the parallel plate capacitor, V is the voltage, and d is the spacing between the electrode and the surface of the attracted object. Therefore, the adsorption force can be adjusted by adjusting the voltage, and the melon seeds with different sizes and different humidity can be adapted.
