Sustainable District Logistics: a Theoretical framework for understanding a new paradigm

An electrostatic actuator according to the present invention includes a first member having a plurality of striped electrodes insulated from one another and arranged in a prescribed direction with a prescribed spacing between them, a second member having a plurality of striped electrodes insulated from one another and arranged in a prescribed direction with a prescribed spacing between them, and continuous-waveform polyphase AC power supplies applied to the electrodes of the first member and the electrodes of the second member, one or both of the first member and second member being moved by an electrostatic coulomb force between the first member and the second member.
