1. A wear sensor, comprising:
a base;
a plurality of conductive layers stacked on the base, the plurality of conductive layers defining a wear surface; and
a plurality of vias extending through each one of the plurality of conductive layers and to the base,
wherein the plurality of vias is electrically connected to electronics to generate a signal through the plurality of vias whereby, upon wear of each of the plurality of conductive layers, a change in the signal of a corresponding via of the plurality of vias at a depth of the wear is detectable.
