Portable Ultrasound Device

Abstract: “PORTABLE ULTRASOUND DEVICE” The present invention describes an ultrasound device (100) that includes a flexible ultrasound transducer (102). The flexible ultrasound transducer (102) comprises a first layer (202), 5 composed of a first flexible polymer, comprising a plurality of piezoelectric plates arranged in an array and configured to emit the ultrasound waves. Further, the flexible ultrasound transducer (102) comprises a second layer (204), composed of a second flexible polymer, stacked on a first surface of the first layer (202). Finally, the flexible ultrasound transducer (102) comprises a third layer (206) stacked on a second surface of the first layer (202) and 10 configured to allow emission of the ultrasound waves to the at least part of the surface of the object, wherein the third layer (206) is a composition of a third flexible polymer and a ceramic material in a predefined ratio and has an impedance value matching an impedance value of the first layer (202).
