Why does touchscreen only work with finger?

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.
