MAGNETIC RESONANCE SAFE ELECTRODE FOR BIOPOTENTIAL MEASUREMENTS

摘要

An electrode patch (34) for use in biopotential measurements in a magnetic resonance (MR) environment includes: a plastic or polymer sheet (32); an electrically conductive trace (58) disposed on the plastic or polymer sheet, the electrically conductive trace having sheet resistance of one ohm/square or higher; and an electrode (30) disposed on the electrically conductive trace and configured for attachment to human skin. In some embodiments the electrically conductive trace is a carbon-based electrically conductive trace. The electrode may comprise a silver or other electrically conductive layer disposed on the electrically conductive trace and an electrolyte layer or other adhesive layer, such as a silver chloride-based electrolyte layer, disposed on the silver or other electrically conductive layer.
