Claim 17:
18. The system of claim 16:
further comprising a baseplate:
arranged below the substrate; and
comprising a set of force drive electrodes:
arranged across the top surface of the baseplate;
arranged in alignment with the set of force sense electrodes at the bottom layer of the substrate; and
configured to capacitively couple the set of force sense electrodes to form a set of capacitive force sensors and effect capacitance values of the set of force sense electrodes responsive to displacement of the substrate toward the baseplate;

wherein the first magnetic element is coupled to the baseplate and facing the first multi-layer inductor; and
further comprising a set of spacer elements, each spacer element in the set of spacer elements:
arranged over a spacer location, in a set of spacer locations, on a bottom surface of the substrate proximal a sensor electrode, in the set of force sensor electrodes;
coupled to a top surface of the baseplate;
supporting the substrate over the baseplate; and
configured to yield to oscillation of the substrate, responsive to the first oscillating voltage across the first multi-layer inductor, during the first haptic feedback cycle.
