Microfluidics controlled tunable coil
View Patent ↗In some example embodiments, there may be provided an apparatus. The apparatus may include a chamber including a first cavity and a second cavity, wherein the chamber further includes a first fluid suspended in a second fluid; a first electrode adjacent to the first cavity; a second electrode adjacent to the second cavity; a third electrode configured to provide a common electrode to the first electrode and the second electrode; and at least one coil adjacent to at least one of the first cavity or the second cavity, wherein an inductance value of the coil is varied by at least applying a driving signal between the common electrode and the first electrode and/or the second electrode. Related methods, systems, and articles of manufacture are also disclosed.
1. An apparatus comprising:
a chamber including a first cavity and a second cavity, wherein the chamber further includes a first fluid suspended in a second fluid;
a first electrode adjacent to the first cavity;
a second electrode adjacent to the second cavity;
a third electrode configured to provide a common electrode to the first electrode and the second electrode; and
at least one coil adjacent to at least one of the first cavity or the second cavity, wherein an inductance value of the coil is varied by at least applying a driving signal between the common electrode and the first electrode and/or the second electrode.
2. The apparatus of claim 1 , wherein the applied driving signal moves the first fluid.
3. The apparatus of claim 2 , wherein the moving causes a change in a permeability of at least one of a core of the coil or a medium adjacent to the coil.
4. The apparatus of claim 1 , wherein the first electrode is in contact, directly and/or through a coating, with at least one of the first fluid or the second fluid.
5. The apparatus of claim 1 , wherein the first fluid and/or the second fluid includes one or more particles and/or one or more nanoparticles having a certain permeability.
6. The apparatus of claim 1 , wherein the driving signal provides a field that affects the move of the first fluid.
7. The apparatus of claim 6 , wherein the field produced by the driving signal includes at least one of an electric field, a magnetic field, and/or a combination of the two.
8. The apparatus of claim 1 , wherein the at least one coil provides at least one of first electrode, the second electrode, and/or the common electrode.
9. The apparatus of claim 1 , wherein the chamber is arranged at least one of on top, below, inlaid and/or within a substrate, and wherein the coil is arranged at least one of on top, below, inlaid, and/or within the substrate.
10. The apparatus of claim 1 , wherein a plurality of cavities are arranged into a chain structure and/or a grid structure, wherein at least one coil is arranged adjacent to at least one of the cavities.
