Abstract
The subject disclosure can facilitate piezoelectrics for energy harvesting. In one example, an article of manufacture (AOM) is provided. The AOM can comprise a piezoelectric fabric comprising: a piezoelectric film; an elastic base on which the piezoelectric film is bonded forming a piezoelectric material; and a yarn, wherein the yarn and the piezoelectric material are coupled to one another in a defined ratio of interlacement. The yarn and the piezoelectric material are configured as coils in some embodiments. In some embodiments, the piezoelectric material is configured such that compression or elongation of the piezoelectric material generates electrical energy. In some embodiments, the AOM further comprises a power management module coupled to the piezoelectric material and configured to store electrical energy received from the piezoelectric material. The AOM can also comprise a rivet, grommet or button coupled to the piezoelectric material or the power management module and configured to capture energy.
