Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The best electrical and mechanical ionogel performance occurs at 5 wt% UiO-66-NH2@PAA and 30 wt% ionic liquid relative to TPU.
Caveat: Exact recipes for each composition are not tabulated in the main text or SI.

The ionogel-based piezoionic sensor shows linear strain-response behaviour and stable output over 3000 bending cycles, supporting wearable motion detection demonstrations.
Caveat: Wearable voltage magnitudes are visual estimates from figures, and long-term stability is reported qualitatively in the main text.

XRD and FTIR evidence supports successful preparation of UiO-66-NH2@PAA and the presence of physical and chemical interactions in the MOF/PAA material.
Caveat: SI microscopy and supplemental FTIR figures were checked; the claim still relies mainly on main-text assignments.

A moderate UiO-66-NH2@PAA loading improves ionogel conductivity, with the authors attributing the optimum to MOF framework ion channels and the decline at higher loading to MOF accumulation/resistivity increase.
Caveat: Figure 2e values are visual estimates and conductivity test geometry is not fully specified in the main article.
50030 · 3.2 · Figure 2e · Linked to 5 structured results
The ionogel can be solvent-recycled through DMAC remoulding because reversible molecular interactions allow the network to reform, although conductivity decreases after recycling due to ionic-liquid loss.
Caveat: Only one recycled-state conductivity and elongation are reported in the main text; repeated recycling cycles are not shown there.
50031 · 3.2 · Figure 3 · Linked to 3 structured results
The sensor voltage is ascribed to pressure-driven ion flux: different cation and anion migration rates redistribute ions under bending, generating a voltage between electrodes.
Caveat: CV, charge-discharge and EIS traces are in the SI, but numerical fitted electrochemical parameters are not tabulated.
