Implantable neural electrodes

The open BCI question is whether an implantable electrode-materials team (graphene, soft conducting polymers, thin-film arrays) holds licensable IP that every implant builder must buy

The callThe implant builders make their own electrodes, so a merchant electrode-materials company has no design-win to point at and a priced-up cohort around it.

  1. D1Brain-computer interfaces move from trials toward standard therapy for paralysis, speech loss and Parkinson's; Neuralink raised at about $9B.
  2. D2Stiff metal and silicon electrodes scar the brain, lose signal over months and can't push enough current through tiny contacts; a soft, stable, high-channel material fixes that.
  3. D3InBrain's first-in-human study implanted 8 of 10 recruited patients with no device failures reported.
  4. R1The builders make the electrode themselves: Precision has FDA clearance for its own thin-film array, Neuralink runs automated in-house manufacturing.
  5. R2The materials cohort is already priced up (InBrain about $124M raised, Axoft a $55M Series A), and a chronic-implant path costs $100M-plus.
  6. R3The one exit on record, Pulse Technologies to Integer, was about $140M.
  7. C1A graphene or soft-polymer supplier wins a disclosed design-win into a third-party implant builder, opening merchant electrode supply.end-2028
