Abstract
Systems and methods are provided for forming a system for transmitting electrical signals to or from the head of a subject. The system includes a base layer. A layer of conductive, non-ferrous material may be deposited along an upper surface of the base layer using a thin-film deposition technique, which is patterned into a conductive trace that extends between a proximal end and a distal end of the base layer. A thick film forming an electrode is positioned relative to a distal end of the conductive trace.
Claims20
A system for transmitting electrical signals to or from the head of a subject, the system comprising:
- a support structure configured for placement on a head of a human subject;
- and
- at least one lead system coupled to the support structure, the at least one lead assembly comprising:
- a base layer having a top surface, a bottom surface, and extending from a proximal end to a distal end;
- an electrical connector attached to a proximal end of the base layer;
- and
- a conductive circuit comprising:
- a conductive trace printed as a thin film along the top surface of the base layer and extending between and electrically connecting the electrode and the electrical connector;
- and
- an electrode formed printed on top of the conductive trace at the distal end of the base layer;
- and
- wherein a height of conductive trace as measured from the top surface of the base layer is less than about 50 nm.
A system for transmitting electrical signals to or from the head of a subject, the system comprising:
- a base layer having a top surface, a bottom surface, a proximal end, and a distal end;
- an electrical connector attached to a proximal end of the base layer;
- and
- a conductive circuit including:
- an electrode supported along the top surface of the base layer at the distal end of the base layer;
- and
- a conductive trace supported along the top surface of the base layer, the conductive trace extending between and electrically connecting the electrode and the electrical connector;
- wherein the conductive trace is formed from a conductive, non-ferrous material deposited along the upper surface of the base layer using a thin-film deposition process, and the electrode is formed as a polymer thick film printed on the conductive trace at the distal end of the base layer.
The system of claim 14, wherein a height of the conductive trace from the top surface of the base layer is about 30 nm or less.
A method of forming a system for transmitting electrical signals to or from the head of a subject, the method comprising:
