Continuous brain function monitoring by high-performance electroencephalogram (EEG) suggests a high impact for advancing precision personalized medication of neurodevelopmental or neurodegenerative disorders. Forehead and ear EEGs are nonhairy recording strategies that allow the activity using only few electrodes. However, they require well-designed electrodes easy comfortable to carry while simultaneously performing durable high-quality EEG acquisition. Herein, we propose new ultrabiocompliant sensor enables seamless contact surfaces both earhole forehead, permitting prolonged signal identification. Bioinspired polydopamine/platinum-silver nanowires, called PDA-Ag@Pt NWs, synthesized with noticeable performances in electrical conductivity, antioxidation ability, cytocompatibility, adhesion. NWs can promote synchronic gelation interlinks within polydopamine-polyacrylamide (PDA-PAM) hydrogels, turn leading one-step formation nanowire/hydrogel matrix, PDA-PAM/NW, as an electrode patch presence adhesive self-healing capabilities. Combined self-designed processor, portable electrophysiological system was realized. The PDA-PAM/NW outperformed commercial terms reliability resolution electrocardiography (ECG), electromyography (EMG), electroencephalography recording. In addition, through cognitive assessment frontal- ear-EEG recording, ultrathin design adhesion make participants over time, subsequently providing identification resolution. This work underscores potential development comfy, long-lasting, wearable brain-machine interfaces revolution neuroscience.
