Guidewire-deployed ECoG arrays for large-area brain–computer interface

• Guidewire-driven deployable ECoG array packs 256 electrodes into 4 cm²; the ultra-flexible thin-film can be folded, pulled through millimetre-sized skull holes, and unfurled epidurally onto dura (arXiv:2511.12907).¹
• In a canine auditory paradigm, the deployed array captured high-quality neural signals used to classify sound types at >80% accuracy across standard ML models.¹
• Authors emphasize biocompatibility for chronic monitoring and resolving coverage–density–invasiveness trade-offs for next-generation BCI.¹
