Devices
A searchable directory of neural interface devices and designs.
This page catalogs devices and research designs, with filters for interface type, anatomy, and use case.
Utah Microelectrode Array (UEA)
A 10×10 silicon intracortical microelectrode array (typically 96 wired channels): excellent spikes early, but challenging chronic stability.
Stentrode (Synchron)
A fully implanted endovascular BCI: a stent-electrode array in the superior sagittal sinus recording ECoG-like signals, trading spikes for catheter-based deployment.
Neuralink N1 (device brief)
Neuralink’s fully implanted, wireless, flexible-thread intracortical system: a high-channel bet on surgical robotics + packaging, with chronic stability still an open question.
Neuropixels Probe
A CMOS silicon intracortical probe family (Neuropixels v1/v2): extremely high-density, low-noise spike recording for animal research; not a chronic human implant.
Spiral nerve cuff electrode (self-sizing / helical cuff)
A foundational, non-penetrating, self-sizing peripheral nerve cuff electrode design family (spiral/helical cuff) widely used for chronic stimulation and sometimes low-SNR recording.
Utah Slanted Electrode Array (USEA)
A penetrating intrafascicular peripheral-nerve array with 100 slanted silicon shanks for high selectivity; enables bi-directional recording/stimulation in human amputees, but with chronic tissue response and percutaneous burden.
FINE (Flat Interface Nerve Electrode)
An extraneural cuff electrode that intentionally flattens/reshapes a peripheral nerve to bring fascicles closer to contacts, improving functional selectivity without penetrating the nerve.
ActiGait implanted drop-foot stimulator (common peroneal nerve multi-contact cuff)
A hybrid implanted-plus-external functional electrical stimulation (FES) system using a multi-contact cuff on the common peroneal nerve to restore ankle dorsiflexion during gait.
TIME (Transverse Intrafascicular Multichannel Electrode)
A flexible thin‑film intrafascicular peripheral nerve interface inserted transversely through a nerve to access multiple fascicles, trading surgical complexity for selectivity.
LIFE (Longitudinal Intrafascicular Electrode)
A classic fine-wire intrafascicular peripheral nerve interface placed longitudinally within a fascicle for selective stimulation and compound action potential (CAP) recording.
CWRU self-sizing spiral nerve cuff (upper-limb sensory stimulation research deployments)
A research-grade self-sizing spiral cuff electrode implementation used in chronic human peripheral nerve stimulation studies, including sensory stimulation in upper-limb amputees.
Neurotrophic Electrode (Kennedy cone electrode)
A biologically integrated intracortical electrode (hollow cone with microwires) designed to encourage neurite ingrowth for long-term single-unit recording in humans.
WIMAGINE (CEA‑Clinatec) epidural wireless ECoG implant
A fully implanted, wireless epidural ECoG system developed by CEA‑Clinatec for human motor BCI research, emphasizing clinical robustness and long-term stability over single-unit precision.
Paradromics Connexus (acute first-in-human recording)
Paradromics’ Connexus intracortical BCI platform, validated in a short intraoperative first-in-human recording and positioned to scale into a chronic, fully implantable communication/speech system.
TEENI-RPNI (tissue-engineered electronic nerve interface – regenerative peripheral nerve interface)
A muscle-mediated peripheral nerve interface (RPNI) used as a biological signal amplifier: reinnervated muscle grafts generate stable, high-SNR EMG for long-term prosthetic control without chronic intraneural electrodes.
Hyperflexible regenerative sieve electrode (Veith et al., 2021)
A hyperflexible regenerative sieve electrode designed to promote neurovascular integration across a transected peripheral nerve interface (rat sciatic model).
Macro-sieve regenerative electrode with transit zones (MacEwan et al., 2016)
A chronically implanted macro-sieve electrode with large transit zones enabling robust axon regeneration and selective stimulation in a rat sciatic nerve transection model.
Microchannel-based regenerative scaffold interface (Srinivasan et al., 2015)
A regenerative microchannel scaffold interface that guides axon regeneration into parallel channels and supports chronic recording/stimulation concepts (rat sciatic amputee model).
Science biohybrid cortical engraftment implant (microwell / waffle device)
A surface cortical biohybrid implant: optogenetically enabled neurons seeded in a microwell scaffold on cortex, with neurites integrating into the brain to transmit information via optical stimulation.
Science biohybrid neuronal-embedded penetrating probe (architecture concept)
A conceptual biohybrid intracortical probe where embedded neurons form the tissue-facing interface; microLEDs and electrodes interact with those neurons while neurites/synapses provide coupling to brain tissue.
