Modified mortar for wireless powered lighting systems

A lighting system embedded in a mortar structure powered by an inductive system is described. Different additives with high magnetic permeability were tested to increase power transference efficiency. The best results were obtained using natural magnetite, therefore the impact of different natural m...

Summary:A lighting system embedded in a mortar structure powered by an inductive system is described. Different additives with high magnetic permeability were tested to increase power transference efficiency. The best results were obtained using natural magnetite, therefore the impact of different natural magnetite concentrations on the mortar mechanical and electromagnetic properties was investigated. The best results were achieved for samples with 75 wt.% of magnetite. With this composition, three proofs‐of‐concept were fabricated to show the potential of the technology.
