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 plurality of energy harvesting components configured to be coupled to a rotatable component in a ring formation along a circumference of the rotatable component, wherein each of the plurality of energy harvesting components includes: a substrate configured to be attached to a surface of the rotatable component; a piezoelectric component coupled to a surface of the substrate, wherein the piezoelectric component is configured to deform in response to a mechanical strain imparted on the piezoelectric component as the rotatable component rotates and generate an electric signal; and an interconnect coupled to the piezoelectric components and configured to conduct the electric signal from the piezoelectric components to a device coupled to the rotatable component.
