Piezoelectric actuator having an array of drive columns |
摘要 |
A piezoelectric actuator has a base, and an array of drive columns separated by grooves and each having a top surface for outputting a displacement force. Each of the drive columns is formed in a unitary body with an underlying portion of the base by a first block of a plurality of green sheets made of a piezoelectric material and stacked together.
