Abstract
An ultrasonic wave generator includes an ultrasound generating assembly, a power supply and a controller. The ultrasound generating assembly includes a thermoacoustic film comprising a carbon nanotube film, a first electrode and a second electrode. The first and second electrodes are connected to opposite ends of the thermoacoustic film. The power supply is configured for powering the ultrasound generating assembly. The controller electrically is coupled to the power supply and configured for alternately powering on and off the ultrasound generating assembly at a frequency of at least 20 kHz.
