How does a voltage detector pen work?

Non contact voltage testers work by detecting the changing electric field around objects conducting an AC current (AC stands for “alternating current”). They do not actually need to make direct contact with the conductor to achieve this. The voltage tester pen detects this voltage through capacitive coupling.
