Patent ID: 7501740

Claim:
A microscale driving unit comprising: a support member; a driven member; a first elongated piezoelectric actuator extending in a first direction from a base end fixed to the support member, said first elongated piezoelectric actuator being fixed to the driven member at a tip end of the actuator; a second elongated piezoelectric actuator extending in a second direction from a base end fixed to the support member, said second elongated piezoelectric actuator being fixed to the driven member at a tip end of the actuator, said second direction being set antiparallel to the first direction; a first electrically conductive member connecting the base end of the first elongated piezoelectric actuator to the tip end of the second elongated piezoelectric actuator; and a second electrically conductive member connecting the base end of the second elongated piezoelectric actuator to the tip end of the first elongated piezoelectric actuator.
