1. An electronic system comprising:
- a trellis pattern of conductors, wherein the trellis pattern of conductors forms a plurality of capacitors, the trellis pattern of conductors comprises a plurality of unit cells, and an area of a first conductor of the trellis pattern of conductors in each unit cell of the plurality of unit cells is greater than an area of a second conductor of the trellis pattern of conductors within each unit cell of the plurality of unit cells;
a processing device, wherein the trellis pattern of conductors is coupled to the processing device, and the processing device is configured to sense a capacitance of each capacitor of the plurality of capacitors; and
a host coupled to the processing device, the host including decision logic to determine a state of the trellis pattern of conductors responsive to a signal that indicates a capacitance, of at least one of the plurality of capacitors, sensed by the processing device.

Abstract
An electronic system includes a processing device and a trellis pattern of conductors coupled to the processing device. The trellis pattern of conductors forms a multiple capacitors and the processing device is configured to sense a capacitance of each of the capacitors. A host is coupled to the processing device. The host includes decision logic to determine a state of the trellis pattern of conductors responsive to a signal that indicates a capacitance of one or more capacitors sensed by the processing device.
