摘要：

PROBLEM TO BE SOLVED: To provide a small acoustic sensor and an ultrasonic probe that can efficiently transmit/receive ultrasonic waves.SOLUTION: An acoustic sensor comprises: an ultrasonic transmitting/receiving element in which a plurality of piezoelectric thin-film parts are arranged in a planar shape wires that electrically connect the plurality of piezoelectric thin-film parts and input/output electric signals and a switching unit that switches at least a portion of the wires to change electric impedance at the time of transmission and reception of ultrasonic waves.COPYRIGHT: (C)2016,JPO&INPIT
