Information @ a Glance

  • Piezo ceramics are fundamentally very simple to use and integrate; their compact size even makes them suitable for integration into so-called labs-on-chip.

  • Simple piezo ceramic disks or rings are mounted onto a metal or silicon disk and, as the most compact bender element, thus control the opening or closing of diaphragm pumps or valves.

  • Piezoelectric ceramics or piezoceramics refer to the family of ceramics with perovskite or tungsten-bronze structures which exhibits piezoelectricity.

  • Piezoelectric ceramics found fast development in late 20th century. The development of metal oxide-based piezoelectric ceramics and other piezoelectric ceramics enabled designers to employ the piezoelectric effect and the inverse piezoelectric effect in many new applications.

  • PI's division for piezo-electric ceramic materials and components - offers a wide selection of piezoceramic components and materials based on modified PZT (lead zirconate titanate) and barium titanate, as well as lead-free piezo ceramics and custom tailored ceramics for many applications.

  • Piezoelectric components may be used as actuators, sensors, generators and transducers.

  • EDO piezoelectric ceramic technology utilizes solid state actuators and sensors to solve a wide variety of active vibration control problems.

  • The basic technology for the manufacturing of piezoceramic components is the pressing of shaped bodies using spray dried granular material. This is achieved using high-capacity presses with upto 1MN compacting force. The shaped bodies are either manufactured true to size, taking into account the sintering contraction or with machining excesses which are removed to achieve the required precision. By using high-production in board diamond sawing equipment, it is possible to manufacture reasonably priced components with a thickness as low as 0.2mm.

  • Piezo actuators are constructed by stacking several piezobulk elements and intermediate metal foils. Afterwards an outer insulation layer made of polymer material is applied.

  • Physik Instruments is market leader for piezo-ceramic drive technology, which is used mainly for high-precision positioning tasks, for example in quality assurance or the semiconductor industry.

  • Piezoceramic actuators in lightweight structures enable a purposeful manipulation of the dynamic and vibroadcoustic structural Behaviour.

  • Piezoceramic bulk elements are manufactured from spray-dried granular material by mechanical hydraulic presses. The compacts are either manufactured true to size, taking into account the sintering contraction or the machining excesses which are then reworked to achieve the required precision.

  • Piezoelectric fabrics are ideally suited to power wearable electronics, an application where bulky batteries are very impractical.

  • The highly compact, integrated piezomotor can provide velocities up to 100mm/s together with high position resolution and high holding force.

  • Piezoceramic materials held a key position as electro acoustic transducers that are used in the construction of ultrasonic probe up to gigahertz.

  • Piezoceramic energy harvesting devices are being explored for their potential in creating self powered devices for wireless sensor networks.
