Abstract:
Applications involving biosignals, such as Electrocardiography (ECG), are becoming more pervasive with
the extension towards non-intrusive scenarios helping targeting ambulatory healthcare monitoring, emotion
assessment, among many others. In this study we introduce a new type of silver/silver chloride (Ag/AgCl)
electrodes based on a paper substrate and produced using an inkjet printing technique. This type of electrodes
can increase the potential applications of biosignal acquisition technologies for everyday life use, given that
there are several advantages, such as cost reduction and easier recycling, resultant from the approach explored
in our work. We performed a comparison study to assess the quality of this new electrode type, in which
ECG data was collected with three types of Ag/AgCl electrodes: i) gelled; ii) dry iii) paper-based inkjet
printed. We also compared the performance of each electrode when acquired using a professional-grade gold
standard device, and a low cost p
latform. Experimental results showed that data acquired using our proposed
inkjet printed electrode is highly correlated with data obtained through conventional electrodes. Moreover, the
electrodes are robust to high-end and low-end data acquisition devices.
