PEDOT:PSS 包覆碳纤维多孔干电极实现无凝胶微伏级神经信号采集
Gel‐Free Capture of Microvolt‐Level Neural Signatures Via a 3D Monolithic Carbon Fiber Dry Electrode
AI 导读
研究报道了一种碳纤维基多孔电极（CFPE），由三维导电网络与 PEDOT:PSS 包覆构成，在毛发覆盖头皮处接触阻抗约 10 kΩ·cm²。
推荐理由
该干电极在无皮肤预处理、无凝胶条件下连续佩戴 6 h 后阻抗仅升至初始值的 1.3 倍，为长时间神经电生理记录提供了可对照的界面方案。
创新点
用 PEDOT:PSS 包覆的三维碳纤维多孔网络替代凝胶湿电极，在无皮肤预处理条件下同时实现低界面阻抗与长时间佩戴的阻抗稳定性，并据此采集到微伏级 FFR 与 LLR 信号。
