High power or high sensitivity piezo components

Noliac Group offers customized high quality piezo bulk/ monolayer components for high power as well as high sensitivity applications.

We design, develop and manufacture high quality piezo components. We offer a high degree of product customization and we are continuously extending our manufacturing capabilities in accordance with customer requirements.

High power for ultrasonic waves
The most important applications of the “hard“ piezo ceramic materials are for the generation of high-powered ultrasonic waves.

Advantages of these materials are:
Moderate permittivity
Piezoelectric high coupling factors
High Q-factors
Very good stability under high mechanical loads and operating field strengths

Further, low dielectric losses facilitate their continuous use in resonance mode with only low intrinsic warming of the component.

Practical examples of their applications can be found in:
Ultrasonic cleaning (typically kHz range)
The machining of materials (ultrasonic welding, bonding, drilling etc.)
Ultrasonic processing (e. g. liquid dispersion)
The medical field (ultrasonic dental scale removal, surgical instruments, etc.)
Sonar technology
High sensitivity for sensoring and electro-acoustic applications
The most important fields of application of the “soft“ piezoelectric ceramics are sensors and electro-acoustic applications (sound transmitters and receivers).

Advantages these materials are:
High piezo modulus
Moderately high permittivity
High coupling coefficients

Practical examples of their applications:
Sensors as classical vibration recorders to detect imbalances of rotating machine parts or in crash detectors in the automotive industry,
Sensors in ultrasonic level measurement and flow rate measurement applications
Sensors in object identification and surveillance (e. g. surveillance sensors for cars, glass tampering detectors, etc.),
Sound transmitters (buzzers)
Sound receivers (microphones)
Sound pickups of musical instruments

We are manufacturing all common piezoceramic shapes, such as discs, rings, tubes, rods, bars and plates including shear mode configurations.

Further, we customize according to dimension tolerances as well as tolerances for dielectric and electromechanical properties.
