Mismatching the curvature of the electrode lead portion may produce unexpected and / or unpredictable resistance to the underlying tissue. In addition, repeated movement of the relevant area of ​​the body may even exacerbate the mismatch. Implants for electrical stimulation require low-resistance conductors for the stimulation electrodes, return electrodes, and interconnects, which typically use metal for the wires and contacts.
