Wireless power from 5G networks could replace batteries


Researchers have uncovered an innovative way to tap into the over-capacity of 5G networks, turning them into “a wireless power grid” for powering Internet of Things (IoT) devices that today need batteries to operate.
The researchers have developed a flexible Rotman lens-based rectifying antenna (rectenna) system capable, for the first time, of millimeter-wave harvesting in the 28-GHz band. The Rotman lens is key for beamforming networks and is frequently used in radar surveillance systems to see targets in multiple directions without physically moving the antenna system.
To harvest enough power to supply low-power devices at long ranges, however, large aperture antennas are necessary. The problem with large antennas is they have a narrowing field of view. This limitation prevents their operation if the antenna is widely dispersed from a 5G base station. ....

On a hot summer day in Connecticut, it’s common to go to a beach-side restaurant, eat some fresh oysters and mussels, and enjoy the crashing of the waves against the sand. For a group of University of Connecticut faculty and a Florida Atlantic University professor, their plan is to skip the beach and the restaurant and use relatives of those delicious animals for another reason filtering the harmful microplastics that end up back in our environment. ....

Jeffrey C. Trinkle has always had a keen interest in robot hands. And, though it may be a long way off, Trinkle, who has studied robotics for more than thirty years, says he s most compelled by the prospect of robots performing dexterous manipulation at the level of a human or beyond.
I ve always felt that for robots to be really useful they have to pick stuff up, they have to be able to manipulate it and put things together and fix things, to help you off the floor and all that, he says, adding: It takes so many technical areas together to look at a problem like that that a lot of people just don t bother with it. ....
