Triboelectricity is the scientific term for the occurrence where two materials come into contact, get electrically charged and then separate from one another. Most of the static electricity that we generate in our day-to-day lives is triboelectric. The polarity and the strength of the charge depend on the materials.

The contact and sliding of MCE triboelectrify the virtual electrode, providing the driving force to actuate the top droplet. Therefore, without any electric input and circuit design, a droplet on the FP surface can be faithfully guided by a copper MCE moving at a constant velocity ( Fig. 1D, fig. S6, and movie S1).

1.2: Triboelectric Effect. In an introductory course, the basic phenomena of electrostatics are often demonstrated with "pith balls" and with a "gold-leaf electroscope". A pith ball used to be a small, light wad of pith extracted from the twig of an elder bush, suspended by a silk thread. Today, it is more likely to be either a ping ...
