Researchers have developed sensors that run on extremely low power thanks to using a home’s electrical wiring as a giant antenna to transmit information.

Using a home's electrical wiring as a giant copper antenna allows for wireless sensors that can communicate over a whole house and run for decades on a single watch battery. The device could be ...
