Abstract: A deformable inductive device includes an elastomer material having at least one deformable electrode and a liquid magnetic core formed in the elastomer material and containing a magnetic liquid. Depending on the device's configuration, the deformable element may be embedded in, attached to, or in close proximity with the liquid magnetic core. In some embodiments, the deformable inductive device may be configured as an inductor, solenoid, or transformer and the deformable electrode is at least partially embedded in the liquid magnetic core, for instance. In another embodiment, the deformable inductive device may be configured as part of a wireless power transfer system which includes a coil and a magnetic backplane having the liquid magnetic core with the coil being attached to or in close proximity to the magnetic backplane.

Abstract: A deformable inductive device includes a magnetic core formed of an elastomer material having magnetic particles dispersed in it and at least one deformable electrode. Depending on the device's configuration, the deformable element may be embedded in, attached to, or in close proximity with the magnetic core. In some embodiments, the deformable inductive device may be configured as an inductor, solenoid, or transformer and the deformable electrode is at least partially embedded in the magnetic core, for instance.

Abstract: Embodiments of the present invention provide a tunable inductor having a magnetic core which has an air gap. In order to vary the inductance of the inductor, the inductor includes a tuner that is moveable relative to the magnetic core in the vicinity of the air gap. An actuator is attached to the tuner which, upon actuation, moves the tuner relative to the magnetic core to thereby vary the spacing between the tuner and the core in the vicinity of the air gap. The variation of the spacing between the tuner and the magnetic core varies the effective air gap of the overall inductor in the desired fashion.
