Their applications have been widely increased in various field of industry : mechanical engineering : tools positioning, clamps, active wedges, damping, active control, generation sonic or ultrasonic vibrations, ... microelectronics : positioning of masks, wafers or magic heads, non magic actuation, circuit breakers, fluids : proportional valves, pumps, ink jet, droplet generators, injectors, optics : mirrors or lenses positioning, focusing, laser cavity tuning, alignme nt or deformation of fiber, scanners, choppers, interferometers, modulators. 外文翻譯 2 Multilayer actuators can be manufactured in a wide variety of sizes. The most mon shape is the rectangular bar. Ring multilayer actuators exist also. The measurements under prestress apply to the stack actuators. This standard relates to d33 actuators, which elongate in the direction of poling and is limited to the static and quasistatic applications. prEN 50ZZZ2 (BTTF 632(CONV)12) Properties of multilayer actuators Part 2: Methods of measurement This standard describes the measurement techniques, which can be applied to measure the properties of Multilayer Actuators, as defined in prEN 50ZZZ1. Multilayer actuators can be manufactured in a wide variety of sizes. The most mon shape is the rectangular bar. Ring multilayer actuators exist also. The measurements under prestress apply to the stack actuators. This standard relates to d33 actuators, which elongate in the direction of poling and is limited to the static and quasistatic applications. prEN 50PPP (BTTF 632(CONV)12) Properties of piezoelectric thick films IEC The IEC, the International Electrotechnical Commission is the international standards and conformity assessment body for all fields of electrotechnology. The standards are maintained by a series of technical mittees that cover a narrow subject area. Most of the standards developed in the IEC are maintained and produced by TC49, Piezoelectric and dielectric devices for frequency control and selection. At present the only active work item related to piezoelectric ceramics seems to be a glossary, IEC 6199442.
