More Information
Summary:In one aspect, the disclosure provides an apparatus for use downhole that includes at least one acoustic sensor. In one aspect, the acoustic sensor includes a chamber and an active element comprised of a quantum tunneling composite in the chamber. In another aspect, the acoustic sensor may further include a pair of conductive layers on a pair of sides of the active element. The chamber is filled with an electrically non-conductive fluid. The active element may be placed in the chamber in a manner that causes the active element to be responsive to acoustic waves along a selected direction or in a manner that enables the active element to be non-directional.
