AI Technical Summary
Existing in-ear electroencephalogram (EEG) signal acquisition devices suffer from poor versatility, signal quality is easily affected by motion artifacts, low spatial resolution, and discomfort when worn.
Design an in-ear multi-channel electroencephalogram (EEG) signal acquisition device. It adopts an electrode structure that combines a silicone earpiece tube and memory foam earplug with a conductive metal fabric, and is equipped with multi-stage signal amplification and filtering. Combined with a 3D-printed earphone shell and motion sensor, it can realize multi-channel signal acquisition and motion status monitoring.
It improves the spatial resolution and acquisition quality of the signal, provides more comprehensive physiological data, is suitable for long-term use and comfortable to wear, and is applicable to scenarios such as sleep detection, cognitive assessment and emotion monitoring.
