An apparatus includes a first nib structure that includes a first main body having a first and a second end. The first end is opposite to the second end. The first nib structure further includes a first nib coupled to the first end. The apparatus further includes a capacitive force sensor coupled to the second end of the first nib structure. The capacitive force sensor is configured to measure more than two levels of force being applied to the first nib. The capacitive force sensor comprises (i) a first plate and (ii) a second plate. 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.
