PICMA® actuators are designed to run at minimized operating voltages. In contrast to most conventional actuators they achieve their nominal motion output at operating voltages significantly below 150 V, in the case of bender-type actuators as low as +/-30V. This property is achieved with particularly thin ceramic layers.
Using modern production technologies, the multilayer actuators can be manufactured in virtually any shape. In doing so, all surfaces are encapsulated with the ceramic insulation (Figure 8).
Various basic shapes with round or triangular cross-sections are available, including insulated center holes on benders, chips and stack actuators.
