WIRELESS METHOD AND SYSTEM FOR TRANSMISSION OF ENERGY AND INFORMATION BY ULTRASOUND IN ELASTIC MEDIUM Russian patent published in 2023 - IPC H02J50/80 H04B11/00 H02J4/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the methods that implement the transfer of information and energy through an ultrasonic channel, as well as systems that implement this method. The invention can be used in devices and systems for data exchange with autonomous transmitting and receiving devices located in a sealed housing or environment opaque to electromagnetic radiation in the radio frequency range, including in conditions of low accuracy of mutual positioning of the transmitting and receiving devices in the case of using portable devices, equipped with easily removable transmitting and receiving modules of piezoelectric transducers.

EFFECT: increasing the efficiency of receiving/transmitting energy and information through an ultrasonic channel in an elastic medium under conditions of low accuracy of the mutual positioning of the transmitting and receiving devices.
