Abstract: A piezoelectric micromechanical ultrasonic transducer (PMUT) includes a diaphragm disposed over a cavity, the diaphragm including a piezoelectric layer stack including a piezoelectric layer, a first electrode electrically coupled with transceiver circuitry, and a second electrode electrically coupled with the transceiver circuitry. The first electrode may be disposed in a first portion of the diaphragm, and the second electrode may be disposed in a second, separate, portion of the diaphragm. Each of the first and the second electrode is disposed on or proximate to a first surface of the piezoelectric layer, the first surface being opposite from the cavity. The PMUT is configured to transmit first ultrasonic signals by way of the first electrode during a first time period and to receive second ultrasonic signals by way of the second electrode during a second time period, the first time period and the second time period being at least partially overlapping.
Abstract translation: 压电微机械超声换能器（PMUT）包括设置在空腔上的隔膜，该隔膜包括包含压电层的压电层堆叠，与收发器电路电耦合的第一电极以及与收发器电路电耦合的第二电极。 第一电极可以设置在隔膜的第一部分中，并且第二电极可以设置在隔膜的第二独立部分中。 第一电极和第二电极中的每一个设置在压电层的第一表面上或接近压电层的第一表面，第一表面与腔体相对。 PMUT被配置为在第一时间段期间通过第一电极传输第一超声波信号，并且在第二时间段期间通过第二电极接收第二超声波信号，第一时间段和第二时间段至少为 部分重叠。
