1. An electrode for a touch sensor, comprisingan array of discontinuous micro-wire conductors establishing a reference mesh;
- a first conductive pattern of continuous micro-wires disposed along a first direction, wherein the conductive pattern is coincident with the reference mesh; and
,a plurality of electrically continuous branching elements electrically connected to the first conductive pattern and extending outward therefrom,wherein the branching elements are coincident with the reference mesh and are comprised of micro-wires,wherein the branching elements include a plurality of different lengths,wherein the reference mesh has a characteristic average cell spacing, andwherein the branching elements satisfy one or both of the conditions;
(i) the distance between branching elements is equal to or greater than at least one characteristic average cell spacing, and(ii) the length of each of the branching elements is equal to or greater than at least one characteristic average cell spacing.

Abstract
An electrode for a touch sensitive device includes micro-wire conductors arranged to define an electrically continuous electrode trunk area, and including branching elements which extend outward from the electrode trunk area. The electrically continuous trunk area is patterned coincident an underlying reference mesh pattern, as are the branching elements.
