Abstract
A time-reversal acoustics system includes a wireless beacon with a piezoelectric element adapted to receive an initial acoustic signal from each of a plurality of transducers combined in a single transmitter and controlled individually by an electronic unit. The initial acoustic signal is transformed by the piezoelectric element into an electromagnetic wave feedback signal and transmitted wirelessly to the receiver connected to the input of the electronic unit. The electronic unit receives the feedback signal and transforms it using the time-reversal principles to generate a driving signal for each transducer. All such driving signals are then sent simultaneously to all transducers to deliver high intensity acoustic energy to the beacon. The invention can be used advantageously to non-invasively recharge implant batteries, control drug eluting from an implant, in an image-guided drug-delivery apparatus, etc.
