Conditions
- a charged, ion-selective nanochannel or nanoporous membrane contains an electrolyte
- a sustained temperature difference drives thermo-osmotic liquid motion along the charged interface
- electrical-double-layer counter-ions are preferentially transported by that flow
- no external electrical bias is required for the measured short-circuit current
- pressure-driven current is absent, negligible or separately controlled when the thermo-driven contribution is attributed

This claim does not itself create a matrix cell. The context below belongs to Thermo-osmosis, the phenomenon it is about.
D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.

Notes
One physical experiment (Zhao et al. 2020): a track-etched polyimide membrane between hot and cold reservoirs gave a streaming current rising linearly with ΔT to 14 nA at 47.5 °C over 0.5 cm², direction set by the surface charge (pH). One paper is demonstrated, not established.
