摘要： A dual-frequency ultrasound transducer, comprising a piezo-electric element bonded to a substrate, has two resonant vibration modes: a low frequency mechanical bending resonance mode and a relatively high frequency thickness resonance mode. The low frequency bending resonance mode occurs when the piezo-electric element is excited, in use, by a voltage which includes a low frequency oscillating component. The high frequency thickness resonance mode occurs when the piezo-electric element is excited, in use, by a voltage which includes a relatively high frequency oscillating component. The transducer may include a mounting arrangement, such as a support ring securing the periphery of the substrate to an underlying base layer that enhances the depth of penetration and focus of the ultrasound.

摘要： An ultrasound transducer patch (100) comprises an array of ultrasound transducers (20) mounted to a flexi-PCB (10) containing multiple tracks (12). Each transducer (20), or a sub-group of the transducers is electrically connected to first and second of the multiple tracks. The flexi-PCB (10) is configured, such as by virtue of cut-out portions (114, 414) or by inherent elasticity, to be bendable a out non-parallel axes. The enables the patch (100) to readily conform to a complex 3D surface such as a portion of a patient's face to ensure efficient transmission of ultrasound energy to a desired area of treatment.
