| 主权项 | 1. A method comprising: providing a piezoelectric element, having a first surface and a second surface opposite the first surface; modifying one of the first surface or the second surface such that radial modes of the piezoelectric element are reduced in operation of the piezoelectric element in a transducer such that the first surface or the second surface opposite the modified one is arranged as a sensing element. | ||
