Abstract Study of polymer dry electrodes in sensing biological signals has received attention as the nature of the polymer to bend that supports electrode’s contact and also avoids skin irritations and allergic reactions. As a polymeric substrate, we have used polyaniline (PANI) as it has very good conductivity, environmental stability, lower price and facile synthesis. Carbon nanotube (CNT) is added to the substrate to increase the overall electrical, magnetic, mechanical, thermal and optical properties. The electrodes for ECG (electrocardiography) are obtained by depositing metal layer on the polymer substrate, etch the metal patterns chemically. The composites of PANI-CNT were characterized by XRD (X-ray Diffraction) and FTIR (Fourier Transform Infrared Spectroscopy). SEM (Scanning Electron Microscopy) was carried on to obtain the surface morphology. The composite are made in to pellets and conductivity of the composites was measured.
