Abstract

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).

一种带有12通道FDMA传输器的90 μ w微型1.2克无线脑电图记录仪，用于长达一个月的连续精神健康监测

这项工作提出了一种一分钱大小的1.2克(包括电池)可穿戴无线脑电图记录仪，用于持续长期的精神健康监测。每个设备有两个12位Σ-Δ adc，峰值ENOB为9.4位。使用902-928MHz ISM频段的12通道FDMA发射机(TX)，可以在24个站点实现并发无缆记录。90µW的功耗使10号助听器电池的续航时间长达一个月。通过与临床级仪器进行闭眼α波和事件相关电位(ERP)测量的比较，验证了系统的功能。
