Claim 0:
1. A method for determining a relative position between arrays of a flexible array device, in which the flexible array device includes a plurality of arrays arranged at a predetermined interval in a deformable substrate, the method comprising:
measuring first capacitance between adjacent arrays;
measuring second capacitance between the adjacent arrays after deformation of the substrate; and
determining a relative position between the adjacent arrays based on the first capacitance measurement value and the second capacitance measurement value,
wherein the first capacitance C1 is calculated by the following Equation,, C

where t denotes a length of each of the adjacent arrays in a direction perpendicular to an upper surface of the substrate, L denotes a length of each of the adjacent arrays in a direction parallel to the upper surface of the substrate, d denotes a distance between the adjacent arrays, and, εr and ε0 represent dielectric constants of the substrate and vacuum, respectively,
wherein the distance between the adjacent arrays is changed after the deformation of the substrate, and the second capacitance measurement value is different from the first capacitance measurement value by the change in the distance between the adjacent arrays.
