Title:
TARGETED ENERGY TRANSMISSION METHOD USING ONE OR MORE ULTRASONIC TRANSDUCERS ON AN IMPLANTABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/151179
Kind Code:
A1
Abstract:
A targeted energy transmission method using an ultrasonic transducer array (101,102) on an implantable device (131) is disclosed. The method includes generating a first ultrasonic wave having at least one frequency and at least one amplitude by at least one ultrasonic transducer (111), transmitting the first ultrasonic wave to the implantable device (131), transmitting an echo signal from the implantable device (131) back to the ultrasonic transducer array (101,102), picking up the echo signal by the ultrasonic transducer array (101,102) such that the one or more ultrasonic transducers (111) acquire a plurality of received signals, coupling the received signals to a processor for generating time reversed signals; and modulating the one or more ultrasonic transducers (111) to generate time reversed waves according to the time reversed signals for transmitting the ultrasonic energy to the implantable device (131), wherein the time reversed waves undergo constructive interference at a location where the echo signal is transmitted from.
