A medical electrode includes a backing layer having a top face and a bottom face, and a shrinkable layer covering at least a portion of the top face of the backing layer. Shrinkage of the shrinkable layer results in flexing of a portion of the backing layer to aid placement and attachment of the electrode to the patient.
