Abstract

The present invention relates to a low-profile ultrasound transducer. The low-profile ultrasound transducer includes a piezoelectric component operative to receive a driving signal from an energy generating module and to emit the driving signal as ultrasonic energy. The piezoelectric component has a front surface and a back surface, and the energy generating module includes a plurality of electronic components. The low-profile ultrasound transducer also includes a lens component directly or indirectly deposited on the front surface of the piezoelectric component. The lens component includes a lens portion and a support portion. The lens portion of the lens component is configured to control the direction and wave pattern of the ultrasonic energy emitted from the piezoelectric component. The support portion of the lens component is configured to hold the piezoelectric component in place and to provide a chamber for housing at least one electronic component of the energy generating module. Methods of use and related devices are also disclosed.
