Integrated measurement systems in actuators of piezosystem jena

Press release from: piezosystem jena GmbH

Typical materials that are used in piezo actuators are made out of industrial ceramics. Those materials are synthetic, inorganic, and ferroelectric. The natural characteristics of these ferroelectric materials contain some properties that could adversely affect positioning tasks. The results of those characteristics are creep and hysteresis.

In order to correct the unwanted effects of creep and hysteresis; actuators manufactured for the highest positioning at piezosystem jena can be equipped with integrated measurement systems. Depending on the application the measurement systems may vary – i.e. capacitive sensors, strain gauges or inductive sensors, measure either the motion of the actuator, or (in products with lever transmission) the motion of the components that the ceramic moves.

With the help of the calibrated closed loop electronics the positioning deviation between target and performance will be corrected in milliseconds. Thereby actuators with an integrated measurement system achieve the best performance in accuracy, highest linearity, and extraordinary stability.

Typical values that can be reached with actuators with capacitive sensors are: resolution

piezosystem jena is a world leading company in the development, design and engineering of piezoelectrical actuator-based positioning systems for micro- and nanopositioning and nano-automation. In addition to the positioning stages the company also offers optical fiber switches as well as the support electronics.
The extensive experience in developing and manufacturing a diverse range of nanopositioning systems enables us to provide special systems and also OEM manufacturing.
The piezo actuators and positioning stages are characterized by a unique precision in the range of nanometer, generate forces of serveral thousand Newton and realize precise positionings in micro seconds.

Objective Positioners Adapted To Meet Your Needs For Industrial Applications
piezosystem jena has extended the objective positioner series MIPOS with two new industry products. Typically objective positioners are firmly mounted directly onto a microscope. Piezosystem also introduces two new systems, which can be screwed on a machine or rail. MIPOS 140: Most installed lens positioners require an undesired extension to the optical axis. The distance between the lens and the sample is shortened. This can lead to collisions between the optics and the
Incremental Trigger Function
Trigger signals dependent on the position of the stage Digital piezo-controllers from piezosystem jena (d-Drive and d-Drivepro) offer flexible control for customized systems such as cameras, illumination systems, optical shutters or external measuring systems. Now, piezosystem jena can offer a comfortable trigger function. Trigger signals can be generated dependent on the position of the stage: • Rising edge • Falling edge • On both edges in the direction of movement An additional function sends out a trigger

Beam Tracking with Mirror Tip- and Tilting Piezostage PKS1
In biology applications a laser beam is used for cell stimulation. First the laser beam is redirected onto 2 mirrors then directed to the cells. An important requirement, to hold the laser beam onto the cell is very difficult to achieve due to thermal effects or external vibration. The position of the laser beam needs to be controlled in real-time to track the motion of the cell. For this task a
