A 90-μW Penny-Sized 1.2-gram Wireless EEG Recorder with 12-Channel FDMA Transmitter for Month-Long Continuous Mental Health Monitoring
This work presents a penny-sized 1.2-gram (battery included) wearable wireless EEG recorder for continuous long-term mental health monitoring. Each device has two 12-bit Σ-Δ ADCs with 9.4-bit peak ENOB. With 12-channel FDMA transmitter (TX) in the 902-928MHz ISM band, concurrent untethered recording can be achieved at 24 sites. 90µW power consumption enables month-long battery life with a size-10 hearing-aid battery. System functionality has been validated by comparing with clinical-grade instrument in measurements of both eye-closed alpha wave and event-related potential (ERP).
