Abstract

One variation of a touch sensor system includes a set of touch layers: spanning a first area; and including a set of electrodes. The system further includes a set of inductor layers: arranged below the set of touch layers; spanning a second area less than the first area; and including a set of spiral traces defining an inductor. The system also includes a magnetic element arranged below the set of inductor layers and defining a first polarity facing the inductor. The system further includes a controller configured to: read a set of electrical values from the set of electrodes; interpret a force magnitude of a touch input based on the set of electrical values; and in response to the force magnitude exceeding a force magnitude, drive an oscillating voltage across the inductor to induce alternating magnetic coupling between the inductor and the magnetic element.
