Mechanism of electrostatic force during electrostatic suspension with optoelectronic feedback control

The method of electrostatic suspension with optoelectronic feedback control is described. The approximate equation of electrostatic attractive force used for electrostatic suspension is given out. This article discusses the relationship between the attractive force and some typical factors, among them, the voltage applied on electrodes, the gap between electrode plate and suspended object, the material of suspended object and so on. In addition, the experimental results of electrostatic forces acting on different suspended objects are presented. The theoretical analysis and experimental results show that the method of electrostatic suspension for both conducting and non conducting objects is practically feasible.
