Abstract

Systems and methods for an energy harvester proximate to a rotatable component of a vehicle's wheel are disclosed. In some embodiments, an energy harvester system includes: a substrate having a first surface configured to contact and interface with a surface of a wheel, and a second surface opposite the first surface; a piezoelectric component configured to produce energy in response to mechanical strain imparted on the piezoelectric component, wherein the piezoelectric component is configured to deform while experiencing the mechanical strain so as to contact at least a portion of the second surface.
