Abstract
Described herein are capacitance sensing devices and methods for forming such devices. A capacitance sensing device includes a substrate and a plurality of electrodes disposed on an area of the substrate to form an active portion of the device. Each of the plurality of electrodes comprises at least one irregular edge formed along a non-linear path. The touch sensor also includes a first plurality of conductors disposed on the substrate. Each of the first plurality of conductors has an end electrically connected to one of the plurality of electrodes. The touch sensor can also include a second plurality of conductors that form a routing channel. Each of the second plurality of conductors has an end electrically connected to a second end of one of the first plurality of conductors. Each of the second plurality of conductors has an end electrically connected to a second end of one of the first plurality of conductors. At least one of the first plurality of conductors or at least one of the second plurality of conductors comprise at least one irregular edge formed along a non-linear path.
