Dr. Tentzeris focuses on advancing electromagnetic research, with interests spanning from 5G+ technologies and sustainable energy harvesting to flexible electronics.
His ATHENA lab at Georgia Tech develops technologies for electromagnetic, wireless, radio frequency (RF), millimeter-wave, and sub-terahertz applications. The research of the multidisciplinary team covers telecommunications, defense, space, automotive, health, and weather/climate applications. The group's research efforts combine inkjet-printing, flexible paper/organic substrates, nanotechnology-based structures, and green energy scavenging.
"We don't just do it for academic research purposes. We're motivated by grand challenges. That means we take a look at what's out there and see what we can do to improve quality of life," said Dr. Tentzeris. "We have considered, for example, the need for implantable electronics, the huge environmental impact of disposed batteries and electronics, and power grid vulnerability to climate change. These are the things that drive us."
In particular, the group is focusing on harvesting energy from 5G networks to wirelessly power Internet of Things (IoT) devices. In effect, the group aims to replace batteries with a "wireless power grid."
"The fact is 5G is going to be everywhere, especially in urban areas. You can replace millions, or tens of millions, of batteries of wireless sensors, especially for smart city and smart agricultural applications," said Dr. Tentzeris.
With this technology, service providers could offer power on demand "over the air." Beyond this research area, the group is also developing backscatter technologies, wearable sensors, origami-based electromagnetic systems, and more.
