Energy-mining Card Treats 5G networks as Wireless Power Grids

Ridgewood NJ, A team from Georgia Tech has unveiled a 3D-printed rectifying antenna that can harvest electromagnetic energy from 5G signals and use it to power devices. The playing card-sized device could turn 5G networks into wireless power grids. It is flexible and works well even when bent. Millimeter-wave energy harvesting has been possible for some time, but it hasn’t been practical due to the large size of previous antennas. The device can harvest more than enough energy to power a range of small sensors and devices by using energy that would otherwise have been wasted.
