Inductor device with light weight configuration

Electronic wearable device including an inductor device with light weight configuration comprising:

• a rectangular prismatic electro-insulating support with three pairs of parallel outer faces defining one axis X, one axis Y, and one axis Z orthogonal to each other perpendicular to said outer faces and defining eight corners, one on each intersection between three orthogonal outer faces;
• a rectangular prismatic magnetic core supported by said electro-insulating support;
• three conductor wire windings arranged orthogonal to each other, wound around the three axis X, Y and Z and surrounding the magnetic core;
• wherein
• the magnetic core is a hollow magnetic core composed by three pairs of sheets, each pair of sheets being composed by two parallel sheets facing each other perpendicular to one of said axis X, Y and Z, and wherein
• each sheet is made of a magnetic material, has two parallel main faces on opposed sides of the sheet, said main faces being surrounded by a perimetral area, said sheet being in contact and attached to the electro-insulating support through one of said main faces, and being in contact with the surrounding orthogonal sheets through said perimetral area.
