Abstract: One variation of a system for a touch sensor includes: a substrate; a baseplate; and spacer elements. The substrate defines support locations. The baseplate spans a bottom layer of the substrate and defines spring elements: aligned to the support locations of the substrate; and configured to yield to displacement of the substrate toward the baseplate responsive to forces applied over the substrate. The spacer elements: are interposed between the support locations and the spring elements; and are configured to compress responsive to forces applied over the substrate. Each spacer element, in the spacer elements, includes: an elastomer element; a first adhesive layer; and a second adhesive layer. The first adhesive layer: is arranged over the elastomer element; and coupled to the bottom substrate layer at a support location. The second adhesive layer: is arranged below the elastomer element; and coupled to the baseplate at a spring element.

Abstract: One variation of a system includes a substrate including: a first layer including a first spiral trace coiled in a first direction; a second layer arranged below the first layer and including a second spiral trace coiled in a second direction and cooperating with the first spiral trace to form a multi-layer inductor; and a sensor layer including an array of drive and sense electrode pairs. The system also includes: a cover layer arranged over the substrate and defining a touch sensor surface; and a first magnetic element arranged below the substrate and defining a first polarity facing the multi-layer inductor. The system further includes a controller configured to drive an oscillating voltage across the multi-layer inductor to oscillate the substrate in response to detecting an input on the touch sensor surface based on electrical values from the set of drive and sense electrode pairs.

Abstract: One variation of a system for detecting inputs at a computing device includes: a substrate including top layer and bottom layers, an array of capacitance sensors arranged on the bottom layer, and an array of support locations adjacent the capacitance sensors; a touch sensor surface arranged over the top layer of the substrate; an array of spring elements coupled to the support locations, configured to couple the substrate to a chassis, and configured to yield to displacement of the substrate downward toward the chassis responsive to forces applied to the touch sensor surface; a coupling plate configured to couple to the chassis adjacent the spring elements and effect capacitance values of the capacitance sensors responsive to displacement of the substrate toward the coupling plate; and a controller configured to interpret force magnitudes of inputs on the touch sensor surface based on capacitance values of the capacitance sensors.
