The ultrasound power transmitter activates a set of transmit ultrasonic transducers in close proximity of an electronic device to be arranged to beam ultrasound energy to the electronic device. Alignment magnets of the ultrasound power transmitter are aligned with corresponding alignment magnets of the electronic device to manage the ultrasound beaming. The ultrasound energy may be converted into electric power to charge the battery of the electronic device. Feedbacks may be provided by the electronic device to the ultrasound power transmitter to increase power transmission efficiency. The ultrasound power transmitter may pair the electronic device with other different electronic devices utilizing ultrasonic signals. A spacer with good ultrasound power transmission properties may be located between the ultrasound power transmitter and an ultrasound power receiver of an intended electronic device to enhance power transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for wireless battery charging utilizing ultrasonic transducer array based beamforming","description":"An ultrasound power transmitter comprising a transmit ultrasonic transducer array has a plurality of transmit ultrasonic transducers.
