Abstract:
An acoustic transducer array comprising:a honeycomb structure having a plurality of cells, each of said cells comprises a piezoelectric transducer; each piezoelectric transducer comprises a stack having at least one piezocomposite element; each piezocomposite element includes a plurality of piezoceramic elements, said piezoceramic elements being arranged parallel to each other; said plurality of piezoceramic elements of said piezocomposite element being encapsulated in a polymeric matrix forming said piezocomposite element; a front planar surface and a back planar surface of said piezocomposite element comprise an electrically conductive layer; and a soft pressure release material is disposed around each stack except on a surface of said stack facing a front surface of said acoustic transducer array.
