1. A method for converting between electrical energy and acoustic energy in a borehole tubular member, comprising:

  • bonding at least one major planar surface of a flexible piezoelectric device having a length, width and thickness, the length and width defining the at least one major planar surface as manufactured, to a curved surface of a borehole tubular member, the flexible piezoelectric device having a mechanical response aligned with one of the length and width, andproducing and/or detecting compression forces in the wellbore tubular member aligned with the surface of the wellbore tubular member with the flexible piezoelectric device.
