Abstract

Objective

This study details the design, efficacy, and usability of a novel wearable, wireless electroencephalography (EEG) sensor designed for extended-duration clinical monitoring in any environment.

Methods

Simultaneous EEG recordings from REMI sensors and a conventional scalp-EEG recording system were conducted across two cohorts: 1) participants undergoing routine epilepsy seizure monitoring and 2) healthy volunteers performing tasks to induce common EEG artifacts. Comparative time and spectral-based analyses were conducted between the recording modalities. Sensor usability was also evaluated.

Results

The temporal dynamics and signal morphology of artifacts and electrographic seizures were visually similar between the REMI sensor and conventional scalp-EEG. Additionally, spectral correlation between the two systems was high across all event types, ranging from 0.86 to 0.94. Patient-reported acceptance was also strong, with 69% of participants rating the sensors as comfortable to wear.

Conclusions

The REMI sensor showed strong agreement with conventional scalp-EEG in the signal characteristics of physiological artifacts and electrographic seizures. The positive comfort feedback further supports the REMI sensors’ everyday utility.

Significance

Although limited in electrode coverage compared to conventional scalp-EEG recording systems, the REMI sensor records comparable high-fidelity EEG data in both time and spectral domains. REMI sensor’s recording quality and wearability facilitate extended-duration monitoring in everyday environments.

一种新型无线可穿戴脑电图传感器的信号质量和可用性对比分析

目的：本研究详细介绍了一种新型可穿戴无线脑电图（EEG）传感器的设计、功效和可用性，该传感器设计用于任何环境下的长时间临床监测。方法用REMI传感器和传统的头皮-脑电图记录系统同时记录两组受试者的脑电图：1)接受常规癫痫发作监测的受试者和2)执行诱发常见脑电图伪影任务的健康志愿者。在记录方式之间进行了比较时间和基于光谱的分析。还对传感器的可用性进行了评估。结果在视觉上，REMI传感器与常规头皮-脑电图在伪影和癫痫发作的时间动态和信号形态上相似。此外，两个系统之间的光谱相关性在所有事件类型中都很高，在0.86 ~ 0.94之间。患者报告的接受度也很高，69%的参与者认为传感器佩戴舒适。结论REMI传感器在生理伪影和电痉挛的信号特征上与传统头皮-脑电图具有较强的一致性。积极的舒适反馈进一步支持了REMI传感器的日常用途。虽然与传统的头皮-脑电图记录系统相比，电极覆盖范围有限，但REMI传感器在时间和频谱域都记录了相当的高保真脑电图数据。REMI传感器的记录质量和可穿戴性便于在日常环境中进行长时间监测。
