| Acoustic Power Transfer (APT) is a wireless power transmission technology that uses sound waves, typically in the ultrasonic frequency range (above 20 kHz), to deliver energy over a physical medium such as air, water or solids. Unlike electromagnetic wireless power systems, APT is not affected by EMI and is especially useful for applications in biomedical implants, underwater systems, and metal-enclosed environments. Not only can APT be used to power systems, it also can transfer data at the same time. | Acoustic Power Transfer (APT) is a wireless power transmission technology that uses sound waves, typically in the ultrasonic frequency range (above 20 kHz), to deliver energy over a physical medium such as air, water or solids.

The power transfer generally consists of three stages: | Acoustic waves are used for transmitting energy.
