Abstract

Acoustic Power Transfer is a relatively new technology. It is a modern type of a wireless interface, where data signals and supply voltages are transmitted, with the use of mechanical waves, through a medium. The simplest application of such systems is the measurement of frequency response for audio speakers. It consists of a variable signal generator, a measuring amplifier which drives an acoustic source and the loudspeaker driver. The receiver contains a microphone circuit with a level recorder. Acoustic Power Transfer could have many applications, such as: Cochlear Implants, Sonar Systems and Wireless Charging. However, it is a new technology, thus it needs further investigation.
