1. A thermal tag for activity monitoring, comprising:
a base layer having a plurality of metal lines to provide a conductive path;
heat point sources connected to adjacent metal lines; and
a pattern layer having one or more infrared emitting features positioned over portions of the conductive path, wherein at least one infrared emitting feature couples to the conductive path to emit a predetermined infrared pattern to indicate an activity.
