Abstract
Various embodiments concern a flexure comprising a base metal layer. The base metal layer can have a void between a first lateral side and a second lateral side. The flexure can further comprise a plurality of traces in an array. The plurality of traces can extend over the void and between the first and second lateral sides. The plurality of traces can comprise a pair of outer traces respectively located on lateral ends of the array and at least one inner trace between the pair of outer traces. The plurality of traces and the first and second lateral sides can be spaced relative to each other such that adjacent traces of the plurality of traces capacitively couple to each other and the pair of outer traces capacitively couple with each other through the first and second lateral sides.
