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).
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.
e-Glass (Zanetti, Aminifar, Atienza; EPFL, 2025) — wearable EEG eyeglasses (2025-11-29)
- id:
zanetti-aminifar-atienza-eglass-2025 - corpus: academic
- form factor: glasses
- creator: Renato Zanetti / Amir Aminifar / David Atienza (EPFL ESL)
- disclosure: Zanetti R, Aminifar A, Atienza D, et al. ‘e-Glass: …’ (wearable EEG monitoring in an eyeglasses form factor with edge ML for seizure detection and cognitive-workload monitoring). Scientific Reports 2025. doi:10.1038/s41598-025-29893-4.
- ip status: unknown
- sensors: sensor-dry-eeg-electrode, sensor-eeg
- algorithms: algo-seizure-detection, algo-cognitive-workload
- prior art notes: Discloses an eyeglasses-form-factor wearable EEG monitor with dry electrodes at the temples / around the ears (temporal/occipital pickup, validated against a reference montage at r≈0.93) and on-device machine learning for two applications — ambulatory seizure detection and cognitive-workload monitoring. Relevant to AR-glasses / smart-eyewear claims reciting ‘EEG electrodes integrated into an eyeglasses frame’ and ‘an on-device classifier operating on the EEG’. Anchor for the glasses × EEG cross-cut. Bounds the application space: temple/around-ear contact supports seizure, drowsiness, attention, SSVEP — not frontal ERP or motor-imagery BCI.
