Q1Domain Verified
A piezoelectric actuator is being designed for a high-frequency vibration cancellation system requiring precise nanoscale displacement control. Which piezoelectric material property is paramount for achieving the highest displacement sensitivity under a given electric field?
Curie temperature
Electrostrictive coefficient
Piezoelectric strain coefficient ($d_{33}$)
Dielectric constant
Q2Domain Verified
During the design of a piezoelectric bending actuator, it is observed that the actuator exhibits significant hysteresis, leading to poor position repeatability. Which factor, if not properly addressed during material selection or fabrication, is most likely contributing to this hysteresis?
High internal mechanical damping of the piezoelectric material
Excessive pre-stress applied during assembly
Inadequate poling of the piezoelectric ceramic
Low mechanical stiffness of the substrate material
Q3Domain Verified
A piezoelectric stack actuator is designed to generate a large blocking force for an industrial clamping application. To maximize the blocking force (the maximum force the actuator can exert when its displacement is constrained), which design parameter of the individual piezoelectric elements is most crucial?
High piezoelectric voltage coefficient ($g_{33}$)
High piezoelectric charge coefficient ($d_{33}$)
Low aspect ratio (height to diameter)
High mechanical compliance
