Patent ID: 7710000

Claim:
An erosion and wear resistant sonoelectrochemical probe configured for high power ultrasonic operation, comprising: a high power acoustic resonator, wherein the high power acoustic resonator comprises: an acoustic body comprising a base and a tip; a transducer coupled with the base and configured to vibrate the acoustic body; a diamond electrode coupled with the tip of the acoustic body and disposed at or proximal to a plane defined by the tip of the acoustic body; and an electrically conducting element or elements coupled with the diamond electrode, wherein the electrically conducting element or elements is/are electrically insulated from the acoustic body and each other; wherein the diamond electrode comprises a central disc of boron-doped diamond surrounded by a region of non-conducting diamond, and wherein the region of electrically non-conducting diamond provides for the insulation of the central disc of the boron-doped diamond from the acoustic body.
