1這些最大值僅對應電池用于其最大室溫位移時,對于較小的位移可以使用更僵硬的樣品,有關指導,請參見下圖。
2基于典型楊氏模量中關于彈簧常數的預測樣品的橫截面積,更長的樣本可能,但最大應用的應變將減少(應變調諧器位移保持相同)。
3常規導線可使用高達?±200 V電壓,更多細節信息請聯系我們進行咨詢。

Applications

Match theory to experiment

Significant recent research effort has been spent investigating the electronic and magnetic properties of materials when subjected to uniaxial strains because it allows a convenient way to compare structure/property relationships as predicted from theory experimentally. See?Uniaxial Strain in Condensed Matter Physics.

Compatible with a wide range of probes

The cryostrain cell is the ideal component for your cryogenic measurement system -? compatible with a wide variety of different probes, including x-ray diffraction, scanning probe microscopy, optical imaging and electrical measurements.

Complementary to existing techniques

The cryostrain cells is an ideal companion to diamond anvil cells, providing a complementary technique while also offering better sample access, positive and negative stresses, and in-situ tunability.

A tried and tested technology

The Cryostrain family is based on a technology that has been used in an laboratory environment for more than two years leading to several publications, including a?recent high profile paper in the journal science.

操作原理
如左側圖中的CS100,顯示了當樣品經受正應變和負應變時,應變計中的運動。為了演示的目的,圖中所示的移動經過高度夸張處理。



溫度補償
壓電陶瓷在冷卻時會沿著其輪詢方向延長,這種延長比壓電陶瓷行程的長度長數倍,意味著除非采取特殊處理,否則當溫度改變時,無法適當地控制應變。低溫應變系列的應變計克服了這一問題,壓電陶瓷的特殊布置抵消了熱膨脹,使應變不受壓電陶瓷的熱延伸影響。



拓展范圍
除了熱補償之外,具有數對彼此對立工作的壓電陶瓷,意味著對比直接膠合到樣品上單個壓電疊堆可以產生更高的位移; 考慮到本質上短壓電行程長度有價值的改進。應變樣品非常容易接近,將樣品安裝在可以最大化角度進入的頂部表面上。例如,當樣品安裝在應變單元上時,掃描探針尖端可以掃描表面。
