The new system, developed at MIT, is designed to identify problem areas in power lines inside homes, as well as identify broken electrical appliances.
Accurately tracking energy use inside homes is a big problem, and a growing number of companies and start-ups have been proposing a solution lately. A new development by the researchers at MIT is a wireless energy efficiency monitoring system that uses magnetic fields generated by electrical appliances and wires to analyze the quality of wiring and the condition of electrical appliances in a home.
The system uses an array of five sensors that can be installed on top of wire insulation throughout the home. A special analytical subsystem is able to determine the most favorable locations for the placement of sensors. Any home appliance can be identified by its characteristic "signature", which the devices leave in the form of specific signals and magnetic fields, according to researchers at MIT. Thus, the researchers have created a whole catalog of such "signatures", which allows the software to determine with particular accuracy the type of electrical appliance and analyze its condition.

At the moment, the new technology is in the prototype stage. According to the creators, the data collected using such a device can be presented using specialized applications, which will allow detailed monitoring of the quality of electrical wiring and the general condition of electrical networks in homes. In addition, the new system will be able to provide users with invaluable advice on how to improve the efficiency of energy distribution in the home.
Testing the new development at a military training base helped save huge amounts of money, the researchers said.
