The disclosure provides an ultrasonic wave acupuncture device, including an ultrasonic source, a liquid lens, an ultrasonic-source controller, a liquid-lens controller, and a power supply. The ultrasonic source is adapted to generate ultrasonic waves. The liquid lens is adapted to focus the ultrasonic waves. The ultrasonic-source controller is electrically connected to the ultrasonic source and generates ultrasonic-source voltage pulses to control the frequency, amplitude, and pulse length of the ultrasonic waves generated by the ultrasonic source. The liquid-lens controller is electrically connected to the liquid lens and generates liquid-lens voltage pulses to control the focal length of the liquid lens to focus the ultrasonic waves on a specific location. The power supply is electrically connected to the ultrasonic-source controller and the liquid-lens controller, so as to provide voltage to the ultrasonic-source controller to control the ultrasonic source, and to provide voltage to the liquid-lens controller to control the liquid lens. The ultrasonic-source voltage pulses generated by the ultrasonic-source controller and the liquid-lens voltage pulses generated by the liquid-lens controller are aligned with each other.

A compound acoustic lens, an ultrasound probe and a medical device that includes the same are described. In some embodiments, a compound acoustic lens for an ultrasound probe includes an outer lens including a first material of a first thickness, and an inner lens mated to the outer lens. The inner lens includes a second material of a second thickness. The overall thickness of the compound acoustic lens is determined as a sum of the first thickness and the second thickness and is less than a thickness of a single-material lens having a same focal length as the compound acoustic lens.

A high frequency ultrasound array having a number of transducer elements that are formed in sheet of piezoelectric material. A frame having a coefficient of thermal expansion that is similar to that of the piezoelectric material surrounds the piezoelectric material and is separated from the piezoelectric material by a filling material. Kerf cuts that define the individual elements in the sheet of piezoelectric material extend across a full width of the sheet. In some embodiments, sub-dice kerf cuts that divide a single transducer element into two or more sub-elements also extend all the way across the width of the sheet. A lens positioned in front of the transducer elements can have a radius machined therein to focus ultrasound signals.
