Abstract
A triboelectric generator include at least two yarns, one of which has been infiltrated with a material having a positive triboelectric affinity and one of which has been infiltrated with a material having a negative triboelectric affinity. The at least two yarns are threaded through holes within a disk so that both of the yarns are disposed on both sides of the disk and pass through the holes within the disk. The at least two yarns are helically wrapped (or “coiled”) together on both sides of the disk. During uncoiling, the moving contact between the two yarns, infiltrated with materials having opposite triboelectric affinities, causes an electrical charge to develop. The generated electrical charge can be conducted away for use as electricity.
