ECE Associate Professor Aatmesh Shrivastava was awarded a patent for creating an “Ultra-low power beamforming wireless power transfer system.”
Abstract Source: USPTO
Wireless power transfer (WPT) efficiency is enhanced using an ultra-low power (ULP) distributed beamforming technique. A phase and frequency offset correction technique is used for beam-forming optimization, a backscattering communication technique is used to reduce power over-head, and a new rectifier and MPT method is used for high efficiency RF-to-DC conversion.
