Imaging compatible electrode-set for measurement of body electrical signals and methods for fabricating the same using ink-jet printing

摘要

This invention relates to devices and methods for measuring and/or recording electrical signals from a body, particularly to devices and methods for recording electrical signals from a body while inside a medical imaging device, such as magnetic field scanner, such as a magnetic resonance imaging (MRI) scanner, or a computerized tomography (CT) scanner, and more particularly to devices, such as headpieces with electrodes and conductive pathways, and methods for synthesis of conductive inks used to fabricate the devices, such as with inkjet printer technology. Inkjet compatible inks may be utilized that employ nanoparticle solutions or metalorganic decomposition to generate metallic depositions, such as of silver, without sintering or other secondary processing in predetermined, including customized, layouts.

主权项

1. A device for measuring electrical activity from a human or mammalian body part comprising:
a flexible substrate, said flexible substrate comprising a substantially planar non-electrically conductive material; a plurality of electrodes disposed on said flexible substrate at a set of predetermined positions physically corresponding to a set of predetermined positions of interest on a body, said electrodes comprising a thin layer of conductive material; an interface connector attached to said flexible substrate adapted to electrically communicate with an electrical signal measuring device; a plurality of conductive traces disposed on said flexible substrate, each of said conductive traces electrically connecting one of said electrodes with an interface connector and comprising a thin layer of conductive material;wherein said conductive traces are spaced on said flexible substrate at a distance from each other that prevents electrical communication between them.
