3.1 General terms
3.1.1 vertical contact
physical touching of two objects having relative movement at right angles to their planes at the point of contact
Note 1 to entry: A vertical contact mode triboelectric energy harvester which converts physical contact to electricity and is comprised of dielectric materials, surface electrode, external load, and air gap between dielectric materials, is shown in Figure 1.
Note 2 to entry: The theories for four working modes of a contact triboelectric energy harvester are shown in Figure 2.
3.1.2 nanogenerator
type of technology that converts mechanical/thermal energy as produced by small-scale physical change into electricity
Triboelectric transducer
3.2.1 contact based energy harvester
energy transducer that transforms physical energy due to deceleration/acceleration of the moving contact into electrical energy
3.2.2 triboelectric effect
type of contact electrification in which certain materials become electrically charged after they come into frictional contact and separation action with a different material
3.2.3 triboelectric series
list of materials, some of which have a greater tendency to become positive (+) and the others have a greater tendency to become negative (-)
3.2.4 triboelectric transducer
energy converter to generate electricity from mechanical energy by means of triboelectric effect
3.2.5 surface roughness
quantified surface texture by the deviations in the direction of the normal vector of a real surface from its ideal form
3.3.3 contact area
area of physical contact of one object with the other object
Note 1 to entry: When two objects touch, a certain portion of their surface areas will be in contact with each other. The contact area is the fraction of this area that consists of the atoms of one object in contact with the atoms of the other object. Because objects are never perfectly flat due to asperities, the actual contact area (on a microscopic scale) is usually much less than the contact area apparent on a macroscopic scale. The contact area can depend on the normal force between the two objects due to deformation.BS IEC 62830-6 pdf download.
