压电机构的组成至少是一个压电促动器和一些额外功能：
> 压电机构可以仅基于一个促动器，其他的自由度由引导机构控制。例如下面介绍的光学相位差促动器（OPDA），一个为欧瑞康（Oerlikon-Contraves Space）的LISA项目开发的宇航级线性压电平台，是基于一个APA®和一个弹性引导的机构。
> 压电机构可以基于多个促动器，提供互补作用。例如，CEDRAT TECHNOLOGIES 的XY压电平台，Y轴压电促动器为X轴促动器提供运动引导，反之亦然。
大多数CEDRAT TECHNOLOGIES的压电机构都是基于标准或定制的放大型压电促动器（APA®）或 平行预应力促动器（PPAs）。它们可用于开发X和XY平台，tip-tilts精密摆台，空心促动器，快门和5或6自由度精密机构。
CEDRAT TECHNOLOGIES的压电机构受益于很多航空航天经验，这本身也是高可靠性和高能量密度设计的选择结果：CEDRAT TECHNOLOGIES的压电促动器具有高度预应力，无弱点（如赫兹枢轴或弯曲铰链）。这提供了几个优点：很好承受外部负荷的能力（如外部振动），高动态（大的带宽能力，从DC到共振频率以上）和长寿命。
CEDRAT TECHNOLOGIES的单片集成（固态）压电机构把一个或多个促动器和引导机构结合在一个部件上，如XY平台。具有紧凑性，低成本和高可靠性的优点。
This mini FSM offers a stroke of 12 mrad and a resonant frequency of 1700 Hz, with a mass of 50 gr. It is a good candidate for all projects involving nano satellites or cube satellites, and is a high end alternative to MEMS, which reliability and resistance to space conditions are still being questioned.
3U CubeSat; nano satellites
Microscanning is a key technique in high-resolution IR imaging field.Two technologies are proposed by CEDRAT TECHNOLOGIES (CTEC): moving a lens with a XY25XS Stage or tilting a mirror with a DTT15XS mechanism.
Micro-scanning, Dithering or Pixel shifting
