本文提出了一种直接显示生物电位电极电极-电解质界面电流分布的方法。首先在生物电极表面涂覆电压响应性絮凝材料。然后，使用电势来激活絮凝物材料的释放，同时相机在电极-电解质界面处获取图像。这种成像方法允许观察电极活性区域的微观电流分布，为优化生物电极设计提供了新的工具。我们的计算和实验数据证明了荧光成像方法的可行性。
A method to directly visualize electrical current distribution at the electrode-electrolyte interface of a biopotential electrode is presented in this paper. A voltage-responsive florescent material is first coated on the surface of a bioelectrode. Then, an electric potential is used to activate the release of the florescent material while a camera acquires images at the electrode-electrolyte interface. This imaging method allows observation of microscopic electrical current distribution at the active area of the electrode, providing a new tool to optimize bioelectrode design. Our computational and experimental data demonstrate the feasibility of the florescent imaging method.
