OG exemplary drawing
 
1. A leadwire for transmitting physiological potentials, the leadwire comprising:
an electrode end configured to be connected to an electrode;
a first conductive layer extending from the electrode end;
a device end configured to be connected to a data acquisition device;
a second conductive layer extending from the device end; and
wherein the first conductive layer is galvanically isolated from the second conductive layer such that the first conductive layer and the second conductive layer form a capacitor that is configured to capacitively transmit physiological potentials from the electrode to the data acquisition device, and
wherein an insulating layer of the capacitor extends a majority of a length of the leadwire.
