SUMMARY
The expansion speed of a piezoelectric actuator can be calculated using the formula: displacement (in micrometers) multiplied by frequency (in hertz) multiplied by 2, then converted to miles. In a specific example, an actuator displacing 20 micrometers at a frequency of 200,000 hertz results in an expansion speed of over 16 mph. Despite the high frequencies, piezoelectric actuators do not achieve speeds approaching the speed of sound due to physical limitations in particle velocity.
