示出了包括压电微型超声换能器（的pMUT）阵列和pMUT阵列的系统。 换能器元件的群体内的粘合强度提供了宽的带宽的总响应分割简并模式形状，而相邻的元件群之间的弱粘结强度，元件群之间的适​​度低串扰 提供。 在实施方案中，在换能器元件的人口不同胶片尺寸提供了高带宽全响应不同的频率响应，而，相邻元件之间人口的不同胶片尺寸的布局，元件群之间适度 提供低串扰来。 在实施例中，椭圆形压电膜，以提供多个高带宽全响应和高效率的响应模式。 点域7A

Illustrating a system including a piezoelectric micro ultrasonic transducer (pMUT) array and pMUT array. Bond strength within the population of the transducer elements, provides a split degenerate mode shape for high-bandwidth total response, on the other hand, weak bond strength between adjacent elements population, a moderately low cross-talk between the elements population provide. In embodiments, different film sizes in the population of the transducer element provides a different frequency response for high-bandwidth full response, whereas, the layout of the different film sizes between adjacent elements population, moderate between elements population to provide a low cross talk to. In embodiments, elliptical piezoelectric film, provides a plurality of response mode for high-bandwidth full response and high efficiency.
