与商业电极相比，适形电极提供与皮肤的柔软且适形的界面，用于降低阻抗、舒适的皮肤接触和改善的信号质量。在本文中，我们提出了共形的微图案化的有机金属（CIPs）电极和我们的调查的影响，穿孔微图案化和PEDOT：PSS涂层。对生物传感器电极进行表征，然后相对于市售现成电极进行体内评价。发现PEDOT：PSS降低了每个电极变体中的总阻抗，导致低频下阻抗降低>97%。在高频阻抗的变化是不显着的控制或$30\ \mu \mathrm{m}$通孔电极，但阻抗显着更大的EPD后为60\ \mu \mathrm{m}$通孔电极。
Conformal electrodes provide a soft and conforming interface with the skin for reduced impedance, comfortable skin contact, and improved signal quality compared to commercial electrodes. In this paper, we present conformal micropatterned organic-metal (CMOM) electrodes and our investigation on the effect of perforation micropatterning and PEDOT:PSS coating. CMOM electrodes were characterized then evaluated in vivo against commercial-off-the-shelf electrodes. PEDOT:PSS was found to reduce the overall impedance in each electrode variant, resulting in a >97% decrease in impedance at low frequencies. The change in impedance at high frequencies was not significant for the control or $30\ \mu \mathrm{m}$ vias electrodes, but the impedance was significantly greater following EPD for $60\ \mu \mathrm{m}$ vias electrodes.
