一种新型压电陶瓷驱动电路浙江大学傅卫压电陶瓷作为一种精度高的工作台微动机构，是不少精密仪器所必不可少的。它利用加在其上面的电压。通过压电晶体的电致伸缩特性，产生与电压相应的形变，推动工作台移动。精度达几至几十纳米，形变总量一般可达几十微米。但它所需电... A new type of piezoelectric ceramic drive circuit Zhejiang University Fu Wei piezoelectric ceramic as a high precision workbench fretting mechanism, is a lot of precision instruments essential. It uses the voltage applied to it. Due to the electrostrictive properties of the piezoelectric crystal, a deformation corresponding to the voltage is generated and the stage is moved. Accuracy of a few to tens of nanometers, deformation generally up to tens of microns. But it needs electricity ...
