Sensor Review, Volume 35, Issue 1, January 2015.
Purpose Current study explores the potential possibility of acceleration in recognition, remedies process of heart disease, and continues electrocardiogram signal acquisition. The textile based ECG electrode is prepared by inkjet printing of activator followed by electroless plating of nickel particle. Design/methodology/approach The electrical resistance shows a range around 0.1 Ω/sq, which sounds quite proper for ECG signal acquisition since the potential difference according to heart activity on skin surface is in milivolt range. Surface modifications of Ni-P-plated polyester fiber were studied by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD. The quality of acquired signal from printed sensors in two sizes of square shape with area of 9 and 16 cm2 compared with the standard Ag/Agcl electrode using commercial electrocardiogram in sitting situation. Findings The comparison of these data led to the consideration of small fabric sensor for better performance and the least disturbance regarding to homogeneity and attenuation in electric field scattering. Employing of these types of sensors in textile surface due to flexibility, will cause the user more freedom of action. Wearable electrocardiogram can be applied to solve the problems of aging population, increasing demand for health services and lack of medical expert. Originality/value In the present research, a convenient, inexpensive and reproducible method for the patterning of nickel features on commercial polyester fabric was investigated. Printed designs with high electrical conductivity can be used as sensor of cardiac receiving signals.
