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. 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 magnetic core with the coil being attached to or in close proximity to the magnetic backplane.

Abstract: A variable capacitor includes a substrate; a plurality of electrodes on the substrate; a phase change material on the plurality of electrodes; and a thermo-modifying element adjacent to the phase change material, wherein the thermo-modifying element changes a temperature of the phase change material. The change in temperature of the phase change material may change a capacitance between the plurality of electrodes. The thermo-modifying element may be integrated into the substrate. The thermo-modifying element may include a heater that raises a temperature of the phase change material to change from a solid state to a liquid state. The thermo-modifying element may include a layer of metal adjacent to the substrate, and wherein when electrical current flows through the layer of metal, the layer of metal forms a resistive heater and raises a temperature of the phase change material to change from a solid state to a liquid state.
