摘要:

We report the development of a new technique manipulating the position of electrically neutral material using electronic signals. Dielectrophoresis, or the translational motion of neutral matter caused by polarization effects in nonuniform electric fields, is used in a geometry analogous to that of a charge‐coupled device. Water droplets and steel ball bearings are stepped between a series of electrodes at velocities on the order of 1 cm/s. We find that the average velocity is roughly proportional to the drive voltage divided by the droplet or bearing radius. A variety of applications are discussed.
