Piezoelectric actuator module for use as modular, active composite component, has two piezo stacks arranged on common carrier and partially molded with plastic, where one piezo stack is formed as active piezo element
The module (13) has two piezo stacks (1, 2) arranged on a common carrier (3) i.e. base plate. One of the piezo stacks is formed as an active piezo element and the other piezo stack is formed as a passive body that is made of metal and/or ceramic. The piezo stacks are partially molded with plastic. A separator e.g. PTFE film, is arranged between the piezo stacks. The separator is provided in surface contact with opposing faces of the piezo stacks. The piezo stacks are designed as multilayer actuators. Independent claims are also included for the following: (1) a method for manufacturing a piezoelectric actuator module (2) a method for manufacturing a piezoelectric actuator.
