PI Ceramic (a division of PI Physik Instrumente) introduces a new family of micro components, including mini transducers, suitable for the most precise applications, including medical imaging, nanopositioning, fiber alignment, and optics/photonics.
One of the latest applications of miniature piezo tube transducers can be found in scanning fiber/scanning catheter endoscopes (SFE). These miniature endoscopes provide laser-based high-resolution video to enable minimally invasive procedures. Miniaturized piezo plates are used to drive pumps for micro-dosing and nano-dosing of drugs. Ultrasonic piezo transducers can be used for bubble detection in dialysis or blood transfusion applications and for atomization of medication (aerosol generation) to name a few.
Piezo ceramic actuators and transducers achieve high dynamics with frequencies up to millions of Hertz and excellent reliability. Various shapes and small dimensions are possible to create precision motion based on crystalline solid-state effects. For example, the new ultra-small piezo tube transducers come in two standard sizes: 0.2/0.5 mm ID/OD (inner/outer diameter) with 4-mm length, and 0.9/1.5 mm ID/OD with 15-mm length.
Custom geometries (length, diameter) and custom materials are available, in addition to the large variety of standard piezo tubes and tubular stack transducers offered by PI. Customers can choose from electrodes applied in thick-film and thin film technology. Other options include multi-segmented electrodes for multi-axis scanning operation and modified response behavior as well as wrap-around contacts for easy integration into a mechanical assembly. Lead-free is also available.
