Devices, systems, and methods for delivering electrical current to the body

An electrode comprising:

• a conductive layer having a first electrical conductivity;
• a first conductive trace coupled to the conductive layer and configured to be electrically coupled to a power source;
• and
• a second conductive trace coupled to the conductive layer at a position spaced apart from the first conductive trace, the first and second conductive traces having a second electrical conductivity greater than the first electrical conductivity,
• wherein a density of conductive traces is higher in a first portion of the electrode than a density of conductive traces in a second portion of the electrode, and
• wherein the electrode is configured such that at least some of an electrical current supplied to the first conductive trace from the power source passes through the conductive layer and to the second conductive trace.
