Abstract:
1. An apparatus, comprising: a first nib structure including a first main body, the first main body having a first end and a second end, the first end of the first main body being opposite the second end of the first main body, the first nib structure further including a first nib coupled to the first end of the first main body; and a capacitive force sensor coupled to the second end of the first main body, wherein the capacitive force sensor is configured to measure more than two levels of force being applied to the first nib, wherein the capacitive force sensor comprises a first plate and a second plate, wherein the second plate is parallel to the first plate and is at a pre-determined distance away from the first plate, wherein the first plate has a first side and a second side, wherein the first side faces the second plate, and wherein the second side is (i) opposite of the first side and (ii) coupled to the second end of the first main body, and wherein the first plate is made of a material that is elastic to bend towards the second plate when the first nib structure transfers at least a portion of a force applied to the first nib.
