Piezoelectrical shaker for vibration excitation with

The use of piezo shakers for vibration excitation has many advantages over conventional methods. Piezo shakers have a higher force potential as a result of their stiffness and their ability to operate at exceedingly higher frequencies. Due to their high power density they can be produced in compact sizes. These small elements can be used for modal analysis of mechanical structures. Massive piezo shakers with a seismic mass can modulate forces up to double-digit Kilonewtons.

Piezo shakers are used in the following applications:
• modal analysis of mechanical structures
• material characterization
research in fatigue strength
• defects analysis (in conjunction with Thermography and Holography)

Geo shaker PiSha 1000/35/150 with seismic mass of 80 kg:
• vibration amplitude: 80 µm
• frequency range: up to 250 Hz
• force modulation: up to ±15 kN

Piezo shakers operate with frequencies up to 100 kHz. Oscillation amplitudes reach values from less than 1µm up to several hundred microns. Generated force modulation can reach up to 50 Kilonewton under blocking conditions. Generally, accelerations can reach several 1000g, and in extreme cases up to 10’000g.

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

To offer you complete systems for your needs, piezosystem jena has engineered and produced a NEW series of Motion Control Stages and High-Power Piezo-Composite Actuators. The new catalog does not only show our proven, ultra-precise nanopositioning piezo stages for positioning with sub-nanometer accuracy and their appropriate controllers; it also incorporates our powerful Piezo-Composite Actuators and their
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

Piezo Ceramics Market Evolving Industry Trends 2025
Piezo ceramics are used to convert mechanical parameters such as pressure, velocity, and acceleration into electrical parameters, or inversely to convert electrical signals into mechanical movement or vibration. Piezo electricity is typically based on the ability of certain crystals to generate an electric charge when mechanically loaded with pressure or tension. This is called the direct piezo effect. Alternatively, if these crystals undergo a controlled deformation when exposed to an
Specialized system – Piezo Micrometer Screw Drive MICI
Hybrid element that combines the advantages of long travel of micrometer screws, with the nm-accuracy of a piezo stage These elements were originally developed for quality control applications in the optics industry. They consist of a piezoelectric actuator in combination with a micrometer screw drive. The user can first adjust the coarse position of the actuator with a micrometer screw, and then fine tune it with the piezo stage itself.
Lead-Free Piezo Material Enters Series Production
PI Ceramic (PIC), a worldwide leading player in the field of actuator and sensoric piezo products, now offers a lead-free piezo material for lead-free ultrasonic transducers. The PIC 700 material is based on bismuth-sodium-titanat (BNT) and is produced as a block by pressing technology. The piezoelectric characteristics are promising: PIC 700 has a high coupling factor for the flexural vibration and is thus suitable as an ultrasonic transducer in the
Piezo-Based Linear Drive for Automation Technology
Linear direct drives have advantages over rotating electric motors for rectilinear motions in automation technology because the latter always have to use a spindle to convert the driving force into translational motion. An often undesirable aspect of conventional linear motors is that they are not self-locking and thus require holding currents which are associated with heat dissipation, high energy consumption and “positional jitter”. Piezo-based linear drives offer a solution here. Physik
