The ability to power remote sensors and devices using Wi-Fi signals could be the enabling technology behind the Internet of things, say electrical engineers.
One of the most significant barriers to deploying sensors, cameras, and communicators is the question of power. The task of fitting a security camera on an external wall or a temperature sensor in an attic immediately runs into the question of how to run a power cable to the device or to arrange for batteries to be replaced on a regular basis.
