NeuroSky MindSet / MindWave (2007) — single dry-electrode consumer EEG headset (2007)
- id:
neurosky-mindset-2007 - corpus: private
- form factor: headband
- creator: NeuroSky, Inc.
- disclosure: NeuroSky, Inc. ‘MindSet’ (and later ‘MindWave’) consumer EEG headset, with the ‘ThinkGear’ single dry forehead (Fp1) electrode and ear-clip reference, output as ‘eSense’ attention and meditation metrics plus raw EEG, first shown 2007.
- ip status: patented
- sensors: sensor-dry-eeg-electrode, sensor-eeg
- algorithms: algo-attention-state, algo-cognitive-workload
- prior art notes: Discloses a low-cost head-worn single-channel dry-electrode EEG device (forehead pickup, ear reference) outputting raw EEG plus derived ‘attention’ and ‘meditation/relaxation’ metrics to a paired device. Anticipates consumer-EEG-headband claims combining ‘a head-worn dry forehead electrode with an ear reference’, ‘on-device band-power feature extraction’, and ‘a derived attention/relaxation index’ from 2007. Product-side anchor for the headband × EEG cross-cut; predates Muse (2014) and Emotiv EPOC (2009).
Emotiv EPOC (2009) — 14-channel wireless saline-electrode consumer EEG headset (2009-12)
- id:
emotiv-epoc-2009 - corpus: private
- form factor: headband
- creator: Emotiv Systems
- disclosure: Emotiv Systems. ‘EPOC’ EEG headset, released December 2009 — a 14-channel (plus 2 reference) wireless headset with saline-felt electrodes covering frontal/temporal/parietal/occipital sites, with SDKs for mental-command, facial-expression and ‘affective’ detections.
- ip status: patented
- sensors: sensor-saline-eeg-electrode, sensor-eeg
- algorithms: algo-cognitive-workload, algo-emotion-recognition, algo-bci-motor-imagery
- prior art notes: Discloses a wireless multi-channel (14+2) consumer EEG headset with saline-wetted contact electrodes at standard scalp sites and on-device/SDK classifiers for mental commands, facial expressions, and affective states. Anticipates multi-channel consumer-EEG-headset claims combining ‘a wireless head-worn array of ≥8 contact electrodes’, ‘wet/saline electrode coupling’, and ‘classification of cognitive/affective state or intent’ from 2009. Product-side anchor for the headband/cap × EEG cross-cut.
Muse headband (InteraXon, 2014) — multi-channel dry-electrode EEG headband for meditation and sleep (2014-05)
- id:
muse-headband-2014 - corpus: private
- form factor: headband
- creator: InteraXon Inc.
- disclosure: InteraXon Inc. ‘Muse’ brain-sensing headband, shipped 2014 — a forehead-band EEG device with frontal (AF7/AF8/Fp1/Fp2-region) and behind-the-ear (TP9/TP10) dry/conductive-rubber electrodes, giving real-time neurofeedback for meditation (and, in ‘Muse S’, sleep tracking).
- ip status: patented
- sensors: sensor-dry-eeg-electrode, sensor-eeg
- algorithms: algo-attention-state, algo-cognitive-workload, algo-sleep-staging
- prior art notes: Discloses a forehead-band wearable EEG device with frontal and behind-the-ear (TP9/TP10) dry electrodes providing real-time neurofeedback for meditation training and (later) sleep staging. Anticipates EEG-headband claims combining ‘a forehead band’, ‘frontal and mastoid/behind-ear dry electrodes’, and ‘real-time feedback on a meditation or sleep state’ from 2014. Note: its TP9/TP10 around-ear pickup is the same general region used by [[zanetti-aminifar-atienza-eglass-2025]] — relevant prior art for around-ear-EEG wearable claims. Product-side anchor for the headband × EEG cross-cut.
