5G Power Harvesting Supports IoT Ideas, Self-Driving Cars

A billion devices supporting a future "Internet of Things" means billions of batteries that have to be replaced, says Georgia Tech senior researcher Aline Eid  in the above video. To address the environmental cost of such enormous battery use, Eid and her team at the Georgia Tech ATHENA lab found a way to turn 5G networks into a wireless power grid. The team's flexible Rotman lens-based rectifying antenna, which harvests power in the 28-GHz band, supports IoT applications in wearables, smart cities, and self-driving cars.
