Techniques and mechanisms for providing a flexible inductor. In an embodiment, the flexible inductor comprises a metal foil or other planar conductor, and inductive bodies disposed on opposite respective sides of the planar conductor. The inductive bodies each comprise a respective flexible suspension media and ferromagnetic particles disposed therein. A thickness of the planar conductor is in a range of 0.1 millimeters (mm) to 0.3 mm. In another embodiment, different layers of one inductive body vary from one another with respect to a thickness, a ferromagnetic material, a suspension media, an average size of ferromagnetic particles or a volume fraction of ferromagnetic particles.

A flexible inductor includes a coil substrate having a first spiral conductor formed in or on a bottom surface, a first magnetic sheet laminated on a top surface of the coil substrate, and a second magnetic sheet laminated on the bottom surface of the coil substrate. The flexible inductor includes a plurality of outer electrodes including a first outer electrode and a second outer electrode that are disposed in a peripheral portion of the bottom surface of the coil substrate, and cutout portions each formed in an area between the first spiral conductor and each of the outer electrodes so as to penetrate through the coil substrate. The first outer electrode is electrically connected to an outermost end portion of the first spiral conductor. The second outer electrode is electrically connected to an innermost end portion of the first spiral conductor.

A method of fabricating an electromagnet includes obtaining a first flexible PCB that includes one or more first conductive coiled traces and obtaining a second flexible PCB that includes one or more second conductive coiled traces. The first flexible PCB is bent into a shape having at least one curve or corner. With the first flexible PCB having been bent into the shape, the second flexible PCB is then bent into the shape: the second flexible PCB is positioned adjacent to the first flexible PCB to conform with the first flexible PCB. The second flexible PCB may substantially surround the first flexible PCB. An electrostatic deflector may be disposed concentrically with the first and second flexible PCBs.

An inductive component has at least one conductor loop arranged on a printed circuit board and at least one core made of inductive material that cooperates inductively with the conductor loop. The printed circuit board comprises an upper face, a lower face and narrow faces, and moreover at least two printed circuit board parts. Each printed circuit board part has a part of the at least one conductor loop. At least one of the printed circuit board parts comprises a first and a second contact portion. The first contact portion is connected to a first face, in particular the upper face, of the second printed circuit board part and the second contact portion is connected to a second face, in particular the lower face, of the second printed circuit board part, which second face is different from the first face.

Mechanisms for providing inductance-based user interface elements are provided. Some implementations of such inductance-based devices may feature very small gaps between the housing and the inductive coil, as well as various features to aid in improving sensor sensitivity and reducing the possibility of false button-push events.

A first conductive pattern made from a conductive material is formed on a first surface that is one surface of a flexible film made from a dielectric material. An adhesive layer is disposed on a second surface opposite to the first surface of the flexible film. A pair of first outer electrodes generates an electric field in an in-plane direction of a composite member composed of the flexible film and the adhesive layer, and causes an electric current to flow through the first conductive pattern.

Disclosed is a flexible coil circuit for a non-destructive inspection probe. The coil circuit is made of multiple layers of thin flexible ceramic material, each ceramic layer having a metallization layer deposited thereon. The circuit is capable of continuous operation at temperatures up to 350 C. The metallized layers are able to slide freely over one another as the probe is flexed, enabling the probe to conform to the circumference of pipes as small as 2 inches in diameter.

An assembly includes an electromagnetic coil with a conductor, and a substrate on which the conductor is arranged. The coil has a core and the conductor extends around the core. The core is formed by a ferromagnetic rivet that is fastened to the substrate.

An inductor bridge is configured to bridge-connect a first circuit and a second circuit to each other, and includes a flexible flat plate base body, a first connector at a first end portion of the base body and connected to the first circuit, a second connector at a second end portion of the base body and connected to the second circuit, and an inductor section in the base body between the first connector and the second connector. The inductor section includes conductor patterns including a plurality of layers. The inductor bridge further includes a bending portion between the inductor section and the first connector, and a slot at an inner side of the bending portion that reduces a thickness of the base body.
