Abstract:
1. An ultrasonic transducer system comprising: a plurality of piezoelectric elements partially covered by a plating material wrapped around each piezoelectric element, two elongated parallel deactivation cuts being formed in a surface of the plating material so as to define a positive electrode and a ground electrode; and a circuit having a first layer, a second layer, and a third layer, a first ground and a second ground being provided in the third layer, and a plurality of first vias, each first via having a first end and a second end, the second end of each first via being operatively connected to a respective one of the first and second grounds, the first vias extending from the first and second grounds such that the first vias pass through the first and second layers, the first end of each first via being operatively connected to the ground electrode of a respective one of the plurality of piezoelectric elements.
