  • Flexible variable frequency ultrasonic therapeutic probe based on thermoacoustic effect of carbon nanotube film
    Patent number: 11766577
    Abstract: A flexible variable frequency ultrasonic therapeutic probe based on thermoacoustic effect of a carbon nanotube film comprises an ultrasonic sound production element, and a heat dissipation layer and an acoustic matching layer located on both sides thereof. The sound production element comprises a carbon nanotube film, metal electrodes and wires, and the shape and size of the sound production element can be adjusted according to the actual functional requirements. When a signal is accessed into the sound production element, the carbon nanotube film produces a corresponding temperature change, which causes the surrounding media to expand and contract and to excite ultrasonic waves. The present invention greatly improves the coupling efficiency between the probe and the subject, reduces the energy loss of ultrasonic waves, and enhances the uniformity of the sound intensity distribution in the affected part.
