Wireless Acoustic Power Receiver for a Load and for Communication

Abstract

The present disclosure relates to a wireless acoustic power receiver comprising an acoustic transducer and a corresponding method of operation. The acoustic transducer is configured to: capture a first alternating current (AC) signal with respectively a first and a second electrode; capture a second AC signal with respectively the first electrode at a first phase and the second electrode at a second phase. The first and the second AC signal are respectively based on vibrations of a first and a second vibration mode of a diaphragm that are respectively induced by a first and a second acoustic frequency. The receiver is configured to provide an electrical power of the first AC signal or the second AC signal to a load, and receive a downlink data stream based on and/or provide an uplink data stream by selectively reflecting and modulating the second acoustic frequency or the first acoustic frequency.
