MULTILAYER COIL ARRAY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18479292 titled 'MULTILAYER COIL ARRAY

The multilayer coil array described in the patent application includes a magnetic layer within an element body, with two coils stacked in a vertical direction within the body, along with outer electrodes and lead-out conductors.

  • The element body contains a magnetic layer.
  • There is a first coil with conductor layers closer to the bottom surface of the element body.
  • A second coil is positioned further from the bottom surface than the first coil.
  • Outer electrodes are present on the bottom surface, connected to the respective coils.
  • Lead-out conductors connect end portions of the first coil to the outer electrodes.

Potential Applications: - This technology could be used in wireless power transfer systems. - It may find applications in magnetic resonance imaging (MRI) machines. - The multilayer coil array could be utilized in electric vehicle charging systems.

Problems Solved: - Improved efficiency in power transfer. - Enhanced magnetic field generation. - Compact design for space-constrained applications.

Benefits: - Higher power transfer efficiency. - Increased magnetic field strength. - Space-saving design for compact devices.

Commercial Applications: Title: "Enhanced Multilayer Coil Array for Efficient Power Transfer" This technology could be commercialized for use in wireless charging pads, medical imaging equipment, and electric vehicle charging stations, potentially revolutionizing the efficiency and performance of these systems in various industries.

Questions about Multilayer Coil Array: 1. How does the positioning of the coils within the element body affect the efficiency of power transfer? 2. What are the advantages of using a multilayer coil array compared to traditional single-coil systems?


Original Abstract Submitted

A multilayer coil array includes an element body including a magnetic layer; a first coil inside the element body and including first coil conductor layers in a stacking direction; a second coil inside the element body at a position further from a bottom surface of the element body than the first coil in the stacking direction and including second coil conductor layers in the stacking direction; first and second outer electrodes on the bottom surface of the element body and electrically connected to the first coil; third and fourth outer electrodes on the bottom surface of the element body and electrically connected to the second coil; and a first lead-out conductor inside the element body and connecting, out of end portions of the first coil, an end portion of the first coil conductor layer closest to the second coil to the first outer electrode.
