Actually, capacitive touch screens do not require to be touched by a body that can source current, rather, they sense when contacted by any conductor (see wikipedia article on capacitive sensing). Since wire is a prototypical conductor, you do not need to touch it to use it as a makeshift stylus.

Capacitive vs. Resistive Touchscreens: What Are the …

2018/11/29· As opposed to the resistive touchscreen, which relies on the mechanical pressure made by the finger or stylus, the capacitive touchscreen makes use of the fact that the human body is naturally conductive. Capacitive screens are made of a transparent, conductive material---usually ITO---coated onto a glass material.
