The Complete Handbook of Stylus Pen Nibs & Refills

Chapter 1: Understanding Stylus Pen Nibs & Refills

Every stylus pen is a lever, and its nib is the point where all that leverage meets the surface. For a graphic designer, the nib is a brush controlled by millimeters of pressure. For a warehouse worker, it is a trigger for a scanner, used hundreds of times a shift. For an architect, it is a pencil that captures a line while a building is still an idea. The nib is not a trivia item or an afterthought; it is the single most important component for translating your physical hand motion into a digital signal. It is also a consumable, subject to wear, contamination, and eventual failure. Understanding how nibs work, what they are made of, and why they interact with a glass or PET screen the way they do is the foundation for every other decision you will make in this category.

At the most basic level, a stylus nib is the physical interface between the hard, smooth world of a screen or digitizer and the complex, human-controlled mechanisms inside the pen barrel. When you press a nib against a screen, you are making a physical contact that must be translated into an electronic signal. There are two broad families of stylus technology that define how this translation happens: capacitive and active. A capacitive stylus works by mimicking the electrical properties of a human finger. Your fingertip conducts a small amount of electrical charge, and a capacitive touchscreen is designed to
