Pressure sensor for a stylus

A pressure sensor for sensing pressure on a tip of a stylus, the pressure sensor comprising:

• a variable capacitor comprising:
• a first electrode coated with solid dielectric layer, wherein a portion of the dielectric layer is patterned with a conductive pad that is exposed;
• a second electrode formed at least in part with elastic material,
• wherein the second electrode contacts the conductive pad patterned on the dielectric layer after a defined threshold contact pressure is been applied on the tip of the stylus;
• and
• a support element that moves together with the tip of the stylus and presses against the second electrode in response to pressure applied on the tip;
• a power supply;
• and
• a capacitance measuring unit,
• wherein the power supply and the capacitance measuring unit establish electrical connection with the second electrode via the conductive pad.
