标题： Piezoelectric-based uniaxial pressure cell with integrated force and displacement sensors

摘要： 我们提出了一种压电驱动的单轴应力装置的设计，适用于常温和低温环境，并且同时包含位移传感器和力传感器。 该装置的直径为46毫米，高度为13毫米。 它可以施加高达约45 $\mu$米的零载位移，以及高达约245牛的零位移力。通过结合施加到样品上的位移和力的知识，可以快速确定样品及其夹具是否仍处于其弹性极限内。 在对氧化物金属Sr$_2$RuO$_4$的测试中，我们发现，在室温下，样品在单轴应力约为0.2 GPa时开始出现严重的塑性变形，而在5 K时，样品的变形在几乎2 GPa时仍保持弹性。 这一结果突显了原位调节的有用性，其中可以在将样品冷却到低温后施加力。 显示英文摘要

摘要： We present a design for a piezoelectric-driven uniaxial stress cell suitable for use at ambient and cryogenic temperatures, and that incorporates both a displacement and a force sensor. The cell has a diameter of 46 mm and a height of 13 mm. It can apply a zero-load displacement of up to ~45 $\mu$m, and a zero-displacement force of up to ~245 N. With combined knowledge of the displacement and force applied to the sample, it can quickly be determined whether the sample and its mounts remain within their elastic limits. In tests on the oxide metal Sr$_2$RuO$_4$, we found that at room temperature serious plastic deformation of the sample onset at a uniaxial stress of ~0.2 GPa, while at 5 K the sample deformation remained elastic up to almost 2 GPa. This result highlights the usefulness of in situ tuning, in which the force can be applied after cooling samples to cryogenic temperatures.
