We commercialize high efficiency(100+x higher) RF energy harvesting technology invented at Carnegie Mellon Univ. Our harvester, released at CES 2020, can generate electricity from ambient RF signals to replace battery, and provide a clean, maintenance-free, wireless powering solution to enable the deployment of billions of IoT sensors. We are now focusing on pilot opportunities in industrial IoT (grant from Shell GameChanger) and Bluetooth IoT (smart city/building efficiency/contact tracing)
