Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Ultraflexible Cu3(HHTP)2 MOFECT arrays can record on-skin ECG signals from multiple directions and produce waveforms comparable to standard multilead ECG directions.
Caveat: Demonstrated on one human subject in the article; clinical diagnostic validation is outside the scope of the reported experiment.

Cu3(HHTP)2 MOFECTs combine high geometry-normalised transconductance, high mu*C* product and balanced electron/hole transport under low operating voltage.
Caveat: Best-value comparisons rely on the authors' selected benchmark set and operating geometry.

Layer-by-layer liquid-phase Cu3(HHTP)2 deposition supports large-area MOFECT arrays with narrow mobility distribution across 16 devices.
Caveat: Uniformity is demonstrated for 16 devices on one reported substrate size; raw device-level data are not tabulated.

Highly oriented Cu3(HHTP)2 thin films provide vertical ion-conductive nanopores, enabling volumetric ion doping, high capacitance and fast MOFECT response.
Caveat: Ion-conductivity extraction relies on the authors' transmission-line model rather than a direct pore conductivity measurement.
main p.4-6 · Figures of merit of MOFECTs · Fig. 3; fig. S15 · Linked to 5 structured results
The crystalline Cu3(HHTP)2 channel shows negligible aqueous-electrolyte swelling and stable pulsed operation, supporting reversible electrochemical transistor use.
Caveat: The stability tests are device-level pulsed tests over 8000 s, not long-term continuous field deployment.

The Cu3(HHTP)2 MOFECT is ambipolar: cations induce n-type behaviour under positive gate bias and anions induce p-type behaviour under negative gate bias; XPS supports predominantly electrostatic rather than redox doping in the operating window.
Caveat: XPS is ex situ and compares selected bias states; it may not capture all operando interfacial changes.
