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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 795,607, filed January 23, 2019, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure generally relates to a method of targeted energy delivery on an implantable device using one or more ultrasound and / or acoustic transducers. In particular, the present disclosure relates to a method for focusing and delivering ultrasound energy to an implantable device. Background technique [0004] With advances in implantable smart technology, especially the use of implantable autonomous sensors and actuators, the need to develop better implantable medical devices increases. One area of ​​research focuses on improving the useful life of implantable medical devices. Traditional implantable devices are limited by the capacity of their power supplies, which are often bulky and need to be replaced fro...
