This paper describes the use of commercially available ceramic capacitors as an alternative for lead-containing and relatively expensive lead zirconate titanate (PZT)- based nanoactuators. A PZT actuator is compared with actuators made from both X5R- and Y5V-type ceramic dielectric capacitors using white light interferometry and a spectrometer. This work is useful because these capacitors can provide an economical nanomotion capability to research laboratories or industrial products. Measuring the displacement of the capacitors is also useful when designing electronic products to ensure undesired operation is not caused by the piezoelectric motion. Additionally, unlike the PZT material, the alternative ceramic materials do not contain lead, which is needed for full compliance with the Restriction on Hazardous Substances (RoHS) initiative.
本文介绍了使用市售陶瓷电容器作为替代含铅且相对昂贵的锆钛酸铅（PZT）基纳米致动器的方法。通过白光干涉仪和分光光度计，将 PZT 致动器与 X5R 和 Y5V 型陶瓷介电电容器制成的致动器进行了比较。这项工作很有用，因为这些电容器可为研究实验室或工业产品提供经济的纳米运动能力。在设计电子产品时，测量电容器的位移也很有用，以确保不会因压电运动而导致误操作。此外，与 PZT 材料不同，替代的陶瓷材料不含铅，这是完全符合有害物质限制（RoHS）倡议的要求。
