What it shows: As long ago as 600 B.C., the Greek philosopher Thales knew that amber, when rubbed, would attract bits of paper and other light objects. Many other substances have this same property and can be electrified by rubbing. The kind of electrification (positive or negative) depends on the substances used.

Lateral Sliding Mode. The structure in lateral sliding mode has the same initial status as that of the vertical contact-separation. When two dielectric films are in contact, a relative sliding in parallel to the surface also creates triboelectric charges on the two surfaces, as shown in Fig. 1b (Wang et al. 2013; Zhu et al. 2013a).A lateral polarization is thus introduced along the sliding ...

Quartz or quartz-feldspars mixtures were the two low-dielectric products in nearly all of the mineral mixtures tested. The dielectric constant of the quartz and feldspars particles measured between 4.0 and 4.5. The ratio of feldspars to free quartz was about 5 to 1. The 100-by 150-mesh size fraction was used in nearly all cases.
