  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.
