摩擦起电效应，也就是通过摩擦的方式使得物体带上电荷。摩擦起电的步骤，是使用两种不同的绝缘体相互摩擦，使得它们的最外层电子得到足够的能量发生转移，摩擦起电后两绝缘体必带等量异性电。

The triboelectric effect (also known as triboelectric charging) is a type of contact electrification in which certain materials become electrically charged after they come into frictional contact with a different material. Rubbing glass with fur, or a comb through the hair, can build up triboelectricity. Most everyday static electricity is triboelectric. The polarity and strength of the charges produced differ according to the materials, surface roughness, temperature, strain, and other properties.
