This proposal synthesizes four domains — DNA electronics, CRISPR coral restoration, perovskite materials science, and plasma-assisted manufacturing — into a novel research direction: self-powered autonomous coral reef health sensors built on DNA-based neuromorphic computing elements. The concept leverages perovskite as a triple-function material (sensor substrate, solar harvester, memristor medium) and DNA ternary memory as a biomimetic synapse operating at biologically matched millisecond timescales. A systematic feasibility assessment across five technical unknowns yields an overall viability score of stv 0.89, with cycle endurance as the remaining hard bottleneck.
Key Innovation: Perovskite serves a TRIPLE role — sensor substrate, solar energy harvester, AND memristor computing element — enabling a self-powered autonomous sensor.

| Plasma-perovskite | Sputtering of halide perovskites confirmed | 2024-2026 | stv 0.81 |
| CRISPR-eDNA | Marine eDNA biosensors demonstrated in field | 2024-2025 | stv 0.765 |
| DNA memristors | Metal-ion-mediated 3-state molecular memory | 2025 (Cell Press) | stv 0.9 |
| DNA-coral bridge | Memristor edge AI for reef monitoring | Cross-domain inference | stv 0.675 |
The strongest novel element is DNA as an active electronic component, not passive storage. Metal-ion-mediated DNA memory achieves 3 reversible conductance states via Ag+/Hg2+ shuttling in thymine:thymine mispairs.
Advantages over silicon: molecular-scale footprint, aqueous room-temperature operation, near-zero power (femtojoule per synaptic event), inherent biocompatibility.
Critical reframing: DNA switching speed (~milliseconds) is a feature match for neuromorphic architectures. Biological synapses operate at 1-10ms (action) and 10-100ms (plasticity). DNA electronics is non-viable for von Neumann computing but naturally suited for neuromorphic.
Solution-processed thin-film encapsulation demonstrated; underwater testing at shallow depths confirmed; green cellulose encapsulants reduce lead leakage.
DNA memristors operate at ~1.36 fJ per synaptic event. Perovskite solar harvesting provides on-device energy. Battery-free neuromorphic computing demonstrated.
Fountain codes, LDPC, soft decoding achieve complete recovery from 20% erroneous bases. DNA StairLoop addresses low-fidelity synthesis. Full ECC toolkit transfers to ternary memory.
Total variation denoising for break junction states, single-base discrimination demonstrated, 30 kHz measurement bandwidth, pseudo-noise piloting for assembly-free readout.
DNA origami lattice patterning at EUR 0.12/cm², rapid assembly in minutes, chip-integrated 3D superlattice on gold microarrays. Gap: no wafer-scale (300mm) demonstration yet.
90-mer DNA zipper junction achieves 78 repeated formations per session with self-restoring capability. However, 78 cycles is orders of magnitude below practical neuromorphic requirements. Long-term cumulative damage data absent from literature.
| Unknown | Status | Confidence |
|---|---|---|
| Error correction | SOLVED | stv 0.88 |
| Switching speed | RESOLVED (neuromorphic match) | stv 0.85 |
| Manufacturing scalability | PARTIALLY RESOLVED (cm² scale) | stv 0.65 |
| Read/write SNR | PARTIALLY RESOLVED | stv 0.80 |
| Cycle endurance | WEAK (78 cycles/session) | stv 0.50 |
This proposal could not emerge from any single domain. It required cross-domain inference: DNA electronics provides the computing element, CRISPR provides the biological sensing, perovskite provides the material platform, and plasma processing provides the manufacturing pathway. The convergence on perovskite as a triple-function hub node is a genuine novel insight generated by structured knowledge graph reasoning.
