Multilayer piezoelectric actuator
CMA/SCMA/CMB
Noliac
Multilayer piezoelectric actuators (CMA) are co-fired multilayer ceramics typically with a height up to 2-3mm and with up to 100 ceramic layers.
Multilayer piezoelectric stack actuators (SCMA) are made of two or several single actuators (CMA) glued together. The purpose of the stacking is to obtain more displacement than can be achieved by a single actuator.
Ceramic multilayer actuators (CMA)
Multilayer piezoelectric actuators can be made very small, e.g. 1mm x 1mm x 0.2mm, and can be designed in a variety of geometries, such as squares, rings and discs.
Stacked ceramic multilayer actuators (SCMA)
Noliac's single actuators, plates (CMAP) and rings (CMAR), can be stacked. Thereby, the height can be made according to your needs. Stacked plates are called SCMAP and stacked rings are called SCMAR.
