Electronics

catalog
Electronic supplies for piezomechanics: An introduction
Provides basic information about electrical behaviour of piezo actuators (capacitive elements).
How is the mechanical response of your piezo actuator like “position”, “velocity”, “acceleration”, ”force” related with the electrical parameters “electrical charge”, “electrical current”, “voltage”.
Hints are given for an optimum combination of actuators and power supplies for reducing self heating and extending the frequency bandwidth of your system.
It is the power supply, what defines the performance of your actuation system !
