Applications

We have collected examples of different types of piezo-based applications in the most common industries using piezo. The examples are listed here to provide inspiration to the wide range of applications that can benefit from the use of piezo, but there are practically no limits to where piezo can be used.

Ultrasonic welding
Ultrasonic welding
Piezos are used for ultrasonic welding with high-frequency ultrasonic acoustic vibrations. The vibrations are applied to two parts by a vibrating tool. The actual welding is a result of the heat and...
High frequency nanopositioning
High frequency nanopositioning
Piezoelectric actuators are used for high frequency nanopositioning, where a small displacement amplitude with a fast response is required. This is the case for example for metrology applications or...
Ultrasonic level measurement
Ultrasonic level measurement
Piezos are used in devices for ultrasonic level measurement, typically in processes utilizing liquids or powders. One of the major advantages of ultrasonic level measurement is the fact that there is...
Flow meters
Flow meters
Piezos are used in ultrasonic flow meters to measure the flow of a fluid. The flow meter can measure the flow velocity, volume or mass flow of pure water, wash water, sewage, process liquids, oils,...
Ultrasonic surgery instruments
Ultrasonic surgery instruments
Piezoelectric transducers are used in ultrasonic surgery instruments, which offer numerous advantages over traditional techniques. Increased safety, visibility, precision, faster healing and more...
Underwater imaging
Underwater imaging
Piezos are used in transducers for underwater imaging systems. Their purpose is to measure and describe targets in the water and on the bottom. They are used also for identification of the features on...
Sonars for underwater communication
Sonars for underwater communication
Piezos are used in sonars for underwater communication, where you benefit from the acoustic waves radiating from the sonar. Acoustic waves are the best solution for underwater communication as a means...
Fishfinders
Fishfinders
Piezos are used in fishfinders, which are sonars directed towards the bottom of a lake or the sea. The fishfinder can display a signal when there is an object (fish, wreck, vegetation, sudden change...
Long range micropositioning
Long range micropositioning
Piezos are used for long range micropositioning. Long range micropositioning is cost effective and can be used for both R&D and industrial purposes. Long range micropositioners are capable of both...
Tunable lasers
Tunable lasers
Piezos are used in tunable lasers, where the output wavelength can be tuned. Tunable lasers rely on the performance of a micropositioning or nanopositioning actuator to position with extreme precision...
Ultrasonic non-destructive testing
Ultrasonic non-destructive testing
Piezos are used in a broad variety of applications for non-destructive testing e.g. cement bond evaluation, casing thickness gauging and flaw detection in pipes and welded joints. Where other testing...
Micro-thrusters for satellites
Micro-thrusters for satellites
Piezos are used in micro-thrusters for satellites, where the micro-thrusters are used to position and stabilize the satellite. Naturally, there is a very strong focus on reliability and functionality...
Ultrasonic cleaning
Ultrasonic cleaning
Piezos are used in ultrasonic cleaning devices, which use ultrasound and a suitable cleaning solvent to clean objects. Ultrasonic cleaning is a fast and effective cleaning method that can clean all...
Ultrasonic level meters
Ultrasonic level meters
Piezos are used in devices for ultrasonic level meters, typically in processes utilizing liquids or powders. One of the major advantages of ultrasonic level meters is the fact that there is no contact...
Structural health monitoring
Structural health monitoring
Piezos are used in structural health monitoring (SHM), where the integrity of mechanical structures is checked while in use. This is highly relevant where safety is an important issue e.g. transport...
Ultrasound scanners
Ultrasound scanners
Piezos are used in ultrasound scanners for medical imaging, for example for pregnancy monitoring. With the ultrasound scanner, the sonographer operating the scanner can view an image of the fetus...
Ultrasonic dental scalers
Ultrasonic dental scalers
Piezoelectric transducers are used in ultrasonic dental scalers for ultrasonic removal of plaque and calculus, which is a more efficient method than traditional scalers.
Low frequency nanopositioning
Low frequency nanopositioning
Piezos are used for low frequency nanopositioning, where a very smooth and frictionless motion and a high level of accuracy are required. Here, a flexure-guided table is indicated, where the flexure...
Interferometers
Interferometers
Piezos are used in interferometry, which is the technique of diagnosing the properties of two or more lasers or waves by studying the pattern of interference created by their superposition. The...
Active vibration damping
Active vibration damping
Piezoelectric actuators are used for active vibration damping in mechanical structures where vibrations are undesirable. Vibration damping can be designed to reduce noise, fuel consumption and energy...
