Contactless energy transfer using acoustic approach - A review

A coupled of ultrasonic transducer can act as a power transmission device by means of Acoustic Energy Transfer (AET). This method is relatively new method of contactless energy transfer and could be an alternative to the currently established technologies for the contactless transmission of power, such as inductive power transfer (IPT) and capacitive coupled power transfer (CPT). This paper presents a review on energy transmission through ultrasonic transducers as a source of power that has been applied by various researchers. Through this review, we hope that a better understanding of AET concept can be established and therefore can have a bright future.
