1. An input device comprising:

  • a first substrate;

    proximity sensor electrodes disposed on the first substrate, the proximity sensor electrodes configured to detect objects in a sensing region;

    a first force sensor electrode disposed on the first substrate; and

    a second substrate physically coupled to the first substrate, the second substrate comprising a spring feature and an electrode component, wherein the electrode component at least partially overlaps the first force sensor electrode to define a variable capacitance between the first force sensor electrode and the electrode component, and wherein the spring feature is configured to facilitate deflection of the electrode component relative to the first force sensor electrode to change the variable capacitance.
