1. A compliant probe for providing an elastic electrical connection between at least two electronic components, comprises:
(a) a first planarized layer comprising at least a first structural material;
(b) a second planarized layer comprising at least a second structural material, wherein the second structural material has a relationship with the first planarized layer selected from the group consisting of:
(1) the second structural material is directly adhered to the first planarized layer,
(2) the second structural material is separated from the first planarized layer by one or more intermediate planarized layers, and
(3) the second material is separated from the first planarized layer by one or more depositions of at least one intervening material;
(c) a third planarized layer comprises at least a third structural material, wherein the third structural material has a relationship with the second planarized layer selected from the group consisting of:
(1) the third material is directly adhered to the second planarized layer,
(2) the third material is separated from the second planarized layer by one or more additional intermediate planarized layers, and
(3) the third material is separated from the second planarized layer by one or more depositions of at least one intervening material,
wherein the second planarized layer is located between the first and third planarized layers in a layer stacking direction,
wherein the second structural material is different from the first structural material and the second structural material is different from the third structural material,
wherein the probe is configured to provide an elastic electrical contact element that provides a conductive path along a length of the probe between at least two electronic components,
wherein each of at least one of the first to third planarized layers comprises at least one core structural material and at least one shell structural material, wherein the at least one of the core structural material and the at least one shell structural material of a respective layer corresponds to the respective structural material selected from the group consisting of the first structural material, second structural material, and third structural material while the other of the at least one shell structural material and at least one core structural material is a different material, wherein the core structural material is laterally surrounded by structural material that is not core structural material on the respective layer and wherein the core structural material extends at least a portion of the axial length of the probe and has a length extending in an axial direction of the probe and has a first edge and a second edge, wherein the probe has first edge and a second edge corresponding with the first and second edges of the core, respectively, wherein the first edge of the core is closer to the first edge of the probe than is the second edge of the core, and wherein, along at least a portion of the length of the core, the second edge of the core is closer to the first edge of the probe than to the second edge of the probe,
wherein the core structural material has a first coefficient of thermal expansion and the shell structural material has a second coefficient of thermal expansion, and
wherein the first coefficient is different than the second coefficient.
