A preload structured piezoelectric actuator is a multilayer stacked actuator built into a preload frame. The frame lets us set the output stroke and blocked force to what an application needs by combining several stacks inside it.

A multilayer stacked actuator lasts a very long time when it is designed in well, and fails quickly when it is not. The main reason is that it has to run under preload: its tensile strength is only about one tenth of its blocked force. Preloaded properly, a stack can pass more than five billion cycles.
Getting the best out of a bare stack takes know-how, and an insufficient design costs you output stroke. With the preload structure we guarantee the performance of the stack inside. The frame is tapped, so you bolt it straight into your setup, and unbolt it just as easily if you need to change it. Housed in the frame, the stack is far more robust in a working rig.
Because it bolts in and out, the actuator can be moved from one setup to the next. Housed in the preload frame the stack survives handling well, so the chance of reusing it is high.
Only a few standard sizes of stacked actuator exist. If you need something outside that, an output stroke above 100 µm for example, you have to order a custom part from the manufacturer, which is expensive and slow, and some manufacturers do not make long stroke stacks at all. We can combine stacks in series or in parallel inside a preload frame to reach the performance you need. The PTK10S90 below is one example.

A piezo actuator has hysteresis, which limits positioning accuracy in open loop. Closing the loop restores linearity, to a degree set by the sensor you use. The example below uses the built in strain gauges as the position sensor with PID control.
