What triggers a touch screen?
This conductive material responds when contacted by another electrical conductor, like your bare finger. When you touch your screen, an electric circuit is completed at the point where your finger makes contact, changing the electrical charge at this location. Your device registers this information as a “touch event.”
Why does only my finger work on a touch screen?
The reason some touchscreens only work with a bare finger lies in the human body’s naturally conductive properties. Capacitive touchscreens such as these rely on conductivity to detect touch commands. If you use a gloved finger or a stylus to control them, they won’t register or otherwise respond to your commands.

Can I make a stylus for my phone?
iPhones, iPads, Androids, Kindles, and many other smartphones and tablets have a capacitive touch screen, which needs an electrical conductor (like the human body) to register where contact is made. You can use just about anything as a makeshift stylus–just be careful not to scratch the screen.
What can I use to write on Iphone?
