1. An triboelectric nanogenerator comprising:
a first electrode layer comprising a first network of conductive nanoparticles arranged on a silanized surface of a first textile substrate;
a second electrode layer comprising a second network of conductive nanoparticles arranged on a silanized surface of a second textile substrate and an electronegative layer applied over the second network of conductive nanoparticles, the first textile substrate able to undergo friction with the electronegative layer; and
a component positioned over the first network of conductive nanoparticles of the first electrode layer and defining a contour, the component coupled with both the first electrode layer and the second electrode layer;
wherein both the first electrode layer and the second electrode layer being electrically charged by the friction between the first textile substrate of the first electrode layer and the electronegative layer of the second electrode layer.
