The method works because the electrical field polarises the electric charge on water molecules in the air around the icy tip and then draws them in electrostatically.

Because the technique uses off-the-shelf wireless transceivers similar to those used in home computer networks, "the cost of this system will be cheaper than existing methods of monitoring breathing, " says Neal Patwari, senior author of a study of the new method and an assistant professor of electrical engineering.

ENGADGET: Researchers use wireless network to monitor breathing, could save lives

Their method was based on the observation that electrical currents will be induced in a conductor (such as water) when it is faced with a magnetic field that varies over time.
