Method & Evidence

AimCan PEDOT-based eutectogel electrode arrays be fabricated with specific dimensions and spacing to achieve enhanced high-resolution electrogastrography (EGG) with improved stability and wearable performance compared to traditional Ag/AgCl electrodes?

MethodExperimental fabrication and performance testing

ProcedureA fabrication technique for soft, 3D-protruded, and conducting eutectogel electrode arrays was developed. The PEDOT eutectogel interface was engineered to enhance conductivity and reduce skin-electrode impedance. A 16-circular electrode array was fabricated with a 15 mm diameter and 30 mm interelectrode spacing, and its long-term stability was assessed under ambient drying conditions. High-resolution EGG signals were recorded before and after a meal.
