Aneela Abrar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multilayer piezoelectric and polymer ultrawideband ultrasonic transducer
    Patent number: 7876027
    Abstract: A transducer for transmitting and receiving ultrasound waves and a method for constructing a transducer. The transducer having layers of a single crystal piezoelectric material stacked in a multilayer arrangement and a polymer material geometrically arranged within each layer to form a 3-1 connectivity piezoelectric and polymer composite. The multilayer arrangement includes at least two layers of different thickness. The structure allows the generation of odd and even harmonics to significantly increase bandwith without reducing signal amplitude or efficiency.
    Type: Grant
