Material, Force Sensitivity and Range¶

Sensible Force Range and Force Sensitivity¶

Note

Sensible force range is limited by the flexure strength.

By adjusting \(\Gamma_{\mathcal{M}}\) we can improve the range.

i.e. reduce the range of deflection, but configure \(\Gamma_{\mathcal{M}}\) to detect smaller deflections

\(\Gamma_{b},\Gamma_{\mathcal{M}}\)

Here, we sweeped 5,000 different parameters per material, totaling 30,000 parameter combinations.
