Abstract
An ultrasonic sensor includes M rows of first capacitance micromachined ultrasonic transducers (CMUTs) and N columns of second CMUTs, where M and N are both greater than 1. Each first CMUT has a plurality of first electrodes, a second electrode, and a third electrode for receiving a reference voltage, a first direct current voltage, and a first alternating current voltage, respectively. A first cavity is formed between each first electrode and the second electrode. Each second CMUT has a plurality of fourth electrodes, a fifth electrode, and a sixth electrode for receiving the reference voltage, receiving a second direct current voltage, and generating a second alternating current voltage, respectively. A second cavity is formed between each fourth electrode and the fifth electrode.
