Adjusting nominal voltage
Noliac can customize the nominal voltage from 45 V and up to match your specific requirements. Our standard nominal voltage range of 60 V to 200 V can be applied to all shapes and dimensions of our piezo actuators.
Adjusting the number of layers to customize the nominal voltage
Noliac materials have a recommended operating electrical field of 3 kV/mm. A standard single layer component made of soft doped material (e.g. NCE51) exposed to such an operating field will result in a 3.5 μm displacement. The single layer component requires 6 kV, and since this is undesirable in many cases, we offer to produce an alternative component with many thinner layers instead of just one layer. A component with 100 layers of 20 μm thickness will give the same displacement as the single layer component, but only 60 V is needed as opposed to 6 kV to reach 3 kV/mm.
