摘　　要：One of the fundamental principles of electrostatics is that an uncharged object will be attracted to a charged object through electrostatic induction as the two approaches one another.We refer to the charged object as a single electrode and examine the scenario where a positive voltage is applied.Because of electrostatic induction phenomenon,single-electrode electrostatics only generates electrostatic attraction forces.Here,we discover that single-electrode electrostatics can generate electrostatic repulsion forces and define this new phenomenon as single-electrode electrostatic repulsion phenomenon.We investigate the fundamental electrostatic phenomena,giving a curve of electrostatic force versus voltage and then defining 3 regions.Remote actuation and manipulation are essential technologies that are of enormous concern,with tweezers playing an important role.Various tweezers designed on the basis of external fields of optics,acoustics,and magnetism can be used for remote actuation and manipulation,but some inherent drawbacks still exist.Tweezers would benefit greatly from our discovery in electrostatics.On the basis of this discovery,we propose the concept of electrostatic tweezers,which can achieve noncontact and remote actuation and manipulation.Experimental characterizations and successful applications in metamaterials,robots,and manipulating objects demonstrated that electrostatic tweezers can produce large deformation rates(>6,000%),fast actuation(>100 Hz),and remote manipulating distance(~15 cm)and have the advantages of simple device structure,easy control,lightweight,no dielectric breakdown,and low cost.Our work may deepen people's understanding of single-electrode electrostatics and opens new opportunities for remote actuation and manipulation.
