Actuators

Noliac develops and produces high quality piezo actuators with market leading performance, reliability and dimensions. All piezo actuators can be custom designed to match specific requirements.

Noliac piezo actuators are made as both monolayer and multilayer products. The multilayer piezo actuators are offered as piezo actuator plates and piezo actuator rings (single elements or actuator stacks) and as high temperature stacks and damage tolerant stacks. Noliac also offers piezo benders as plate, ring and in a 2D version. The multilayer piezo actuator is also made as an amplified actuator, and Noliac also produce a piezo motor, the PAD.

The monolayer piezo actuators are offered as shear plate and shear stacks.

All Noliac's piezo actuators are shown below.

Plate actuators
Plate actuators
Noliac multilayer piezo plate actuators feature linear displacement at very low operating voltages. The plates are produced with a stroke up to 3.3 µm.
Ring actuators
Ring actuators
Noliac multilayer piezo ring actuators are produced with a stroke up to 3.3 µm. The piezo ring actuators are used in a wide range of applications due to the easy integration of a ring.
Plate stacks
Plate stacks
Noliac multilayer piezo plate actuator stacks can be stacked to fit the needed height or stroke. Maximum height and stroke are 150 mm and 244.2 µm for our standard products.
Ring stacks
Ring stacks
Noliac multilayer piezo ring actuator stacks can be stacked to fit the needed height or stroke. Maximum height and stroke are 200 mm and 326.7 µm for our standard products. The ring stacks are used in...
High temperature stacks

2D actuators
2D actuators
Noliac 2D multilayer bender actuators are capable of moving up, down, right and left, or as a single or double s-morph. The piezo design is scalable in terms of stiffness, displacement and dimensions.
Shear plate actuators
Shear plate actuators
Noliac shear plate actuators are more compact and have higher resonant frequencies than conventional actuators. They achieve a peak-peak stroke of 1.5µm. The monolayer piezo shear plates also require...
Shear stacks
Shear stacks
Noliac shear stacks are available as single-axis and multi-axis actuators with a stroke of up to 9 µm. Their low capacitance results in reduced power requirements for a given generated displacement....
Amplified actuators
Amplified actuators
Noliac amplified piezo actuator is a compact solution with a high resonance frequency. The multilayer actuator features a low form factor and provides medium stroke and blocking force. It offers push...
Motor/PAD
Motor/PAD
Noliac offers a unique motor called the Piezo Actuator Drive (PAD). The PAD is a drive technology transforming the linear motion of high performance piezoelectric multilayer actuators into a powerful...
