Abstract
A power transmission system using directional ultrasound for power transmission includes a transmitting device and a receiving device. The transmitting device has a set of ultrasound transducers forming an ultrasound transducer array, wherein the array is a set of spaced individual transducers placed in the X-Y plane disposed to generate an ultrasound beam in the Z direction.
Claims10
A power transmitting device of wireless power transmission system using ultrasound, comprising:
- a power processor receiving power from a power source;
- and
- an ultrasound power unit using power derived from the power source for generating at least one directional ultrasound beam, the ultrasound power unit including:
- a set of ultrasound transducers forming an ultrasound transducer array, wherein the array is a set of spaced individual transducers placed in the X-Y plane disposed to generate an ultrasound beam in the Z direction.
