Concrete-embedded wireless power transfer coil

Abstract

The present disclosure covers apparatuses and associated methods for embedding a wireless power transfer coil in concrete. In embodiments, a wireless power inductor pad embedded in concrete includes a wireless power inductor pad comprising a first and second layer of continuously strung stranded wire, each layer arranged in a circular pattern. The first layer is positioned above the second layer such that the stranded wire of the first layer is offset vertically from the stranded wire of the second layer by a vertical wire-to-wire distance. Additionally, the first layer is offset horizontally from the second layer such that the stranded wire of the first layer is offset horizontally from the stranded wire of the second layer by a horizontal wire-to-wire distance; the horizontal wire-to-wire distance being zero inches. Finally, concrete permeates between the first and second layers and between the stranded wires of each layer.
