The Influence of Low‐Temperature Vacuum Environment on Piezo Nano‐Positioning Products & the Corresponding Recommendations People often ask questions like this: Does the low‐temperature vacuum environment have any effect on piezo products? Can piezo ceramics withstand low temperatures? So today we will talk about the effects of low temperature on piezo ceramics. First of all, it is certain that piezo ceramics can be used at low temperatures, and CoreMorrow can provide piezo ceramics for use at low temperatures of ‐273°C. But we need to understand that the piezo effect of piezo ceramics will be reduced when the temperature is lower than room temperature, and the output and displacement that the piezo ceramics can produce will also be greatly reduced. When the low temperature is <260K, the loss is about every K. 0.4%, in the environment of liquid nitrogen, the displacement of piezo ceramics is about 10% of the displacement at room temperature. The displacement curve of piezo ceramics with decreasing temperature is shown in the figure below. For different piezo materials, the curve will change.
Compared with the room temperature environment, the displacement corresponding to different
