Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: Medium

The MOF-MSMC-5h sensor can monitor pulse, temporomandibular pressure changes, and spatial pressure-temperature distributions in a 3 x 3 array.

Caveat: Application demonstrations are qualitative; no long-term implanted device performance reported.

481 · Dual-Modal Applications · Figure 2; Figure 5 · Linked to 4 structured results

Application RelevanceSupport assessment: Medium

The PDMS-sealed MOF-MSMC implant was classified as no inflammatory reaction in the rat histology scoring used here.

Caveat: Small animal-number table; tested sample average has minor fatty infiltration/neovascularization/fibrosis scores.

478 · Pressure-Sensing Properties · Figure S11; Table S4 · Linked to 3 structured results

Composite RoleSupport assessment: High

Changing the substrate from MSMC to PP produces a flatter Ni3(HiTP)2 film and markedly lower pressure sensitivity.

Caveat: PP control has different PDMS curing constraints.

477 · Pressure-Sensing Properties · Figure S5; Figure S6 · Linked to 3 structured results

Phase AssignmentSupport assessment: Medium

Continuous conductive Ni3(HiTP)2 MOF film was successfully grown on MSMC by liquid-solid interfacial growth.

Caveat: Conductivity is cited from prior reports; XRD peak values are not tabulated in the SI text layer.

476 · Results and Discussion · Figure 1; Figure S1 · Linked to 3 structured results

Structure Property LinkSupport assessment: High

The rough, fibre-like Ni3(HiTP)2-MSMC morphology and high Ra of the 5 h film produce the best pressure-sensing performance.

Caveat: Correlation across three growth times and PP control; not a mechanistic isolation of every variable.

477 · Pressure-Sensing Properties · Table S1; Table S2; Figure S2 · Linked to 4 structured results

Structure Property LinkSupport assessment: High

The MOF-MSMC composite suppresses stretch interruptions because its Young modulus is larger than PDMS and tensile strain hardly changes resistance or thermocurrent.

Caveat: The strain-interference results are mostly qualitative from SI plots.

481 · Conclusion · Figure S8; Figure S13 · Linked to 4 structured results

Transport MechanismSupport assessment: High

Pressure sensing and temperature sensing are mutually noninterfering because pressure changes carrier migration paths while temperature sensing reflects carrier energy differences.

Caveat: Supported by device experiments plus COMSOL/DFT calculations; raw simulation files were not provided.
