This document discusses capacitive elements including a first, second and third electrode arranged in a stack. The third electrode is positioned between the first and second electrode. An interconnect includes a unitary substrate shared with the first and second electrodes. The interconnect is adapted to deform to accommodate the stacked nature of the first and second electrodes. The unitary substrate includes a sintered material disposed thereon.
