Abstract
A coil has 1st to Nth turns. The 1st to Nth turns respectively provided with actuation parts for current in one direction to flow, and connection parts for current in the opposite direction to the one direction to flow. The plurality of actuation parts are arranged substantially parallel to each other, and are arranged along a surface of an object or a surface that approximates to the surface of the object. A plurality of connection parts are arranged within a space in which the connection parts do not face the surface of the object over the actuation parts of the 1st to Nth turns, and the connection parts are positioned at the sides with respect to the extension direction of the actuation parts.
Claims13
A coil, adapted to be arranged close to an object, for causing an induced electrical field to be generated inside the object, the coil comprising:
- a plurality of conductor turns comprising:
- actuation parts arranged in parallel to each other, along a surface of the object or along another surface that is close to the surface of the object, for flow of an electrical current in one direction, and
- connection parts arranged within a space in which the connection parts do not face the surface of the object over the actuation parts at a side of the coil, with respect to an extension direction of the actuation parts, for flow of the electrical current in a direction opposite to the one direction;
- and
- a core member which is configured to reduce a magnetic resistance of a magnetic circuit that is generated by the plurality of conductor turns, and arranged at an opposite side to the object, over the actuation parts.
A coil, adapted to be arranged close to a surface of an object, for causing an induced electrical field to be generated inside the object, the coil comprising:
- a core member, and
- a plurality of conductor turns which are formed to continuously extend from an input terminal of the coil to an output terminal of the coil,
- wherein the plurality of conductor turns comprises:
- (1) a plurality of actuation conductor parts used in generation of the induced electrical field, and
- (2) connection conductor parts that connect the plurality of actuation conductor parts together, and that are configured to minimize an effect of the connection conductor parts on an intensity of the induced electrical field generated by the plurality of actuation conductor parts,
- wherein the core member is configured to reduce magnetic resistance of a magnetic circuit generated by the plurality of conductor turns and arranged at an opposite side to the object over the plurality of actuation conductor parts.
A magnetic stimulation device comprising:
- a support;
- a coil, adapted to be arranged close to a surface of an object, for causing an induced electrical field to be generated inside the object, and comprising:
- a plurality of conductor turns comprising:
- actuation parts supported by the support and arranged substantially parallel to each other, for flow of an electrical current in one direction, and
- connection parts arranged in the coil laterally with respect to an extension direction of the actuation parts, for flow of the electrical current in a direction opposite to the one direction,
- wherein the support comprises:
- first grooves configured to accommodate the actuation parts and carry out an alignment of the actuation parts, and
- second grooves configured to accommodate the connection parts and carry out an alignment of the connection parts.
