  2. Triboelectric effect - Wikipedia

    en.wikipedia.org/wiki/Triboelectric_effect

    The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.
