1. A flexible electronic sensor array apparatus comprising:
a continuous flexible sheet having a length defining a first axis, a width defining a second axis and a thickness comprising a third axis;
wherein the flexible sheet comprises multiple flexible sheet layers formed of one or more flexible materials stacked along the third axis;
a plurality of electronic sensors disposed within the flexible sheet, each respective sensor comprising at least two conductive pattern layers formed of an electrically conductive material, the two conductive pattern layers of the respective sensor being spaced apart from one another along the third axis by at least one of the flexible sheet layers interposed between the conductive pattern layers; and
wherein each respective sensor of the plurality of sensors is disposed at a different respective position along at least one of the first axis and the second axis of the flexible sheet from the remaining sensors, thereby forming an array of sensors spaced along the first and second axes within the flexible sheet;
wherein at least some of sensors of the plurality of electronic sensors are flexible thermistor temperature sensors;
wherein the conductive pattern layers of the respective flexible thermistor temperature sensors are metal pattern layers connected to one another by conductive vias formed through the intervening flexible sheet layers.
