Abstract

Highlights: The work developed combines flexible electronics with reconfigurable electronics. Laser-Induce Graphene flexible electrodes improve ergonomic for the user. Remote monitoring with several biosignals is possible only changing the electrodes and the configuration. The device is able to measure Electrocardiogram, Electrooculogram, Electromyogram. The device has performance close to commercial instruments for the acquisition of those signals. Abstract: In this work a versatile hardware platform based on reconfigurable devices is presented. This platform it intended for the acquisition of multiple biosignals, only requiring a reconfiguration to switch applications. This prototype has been combined with graphene-based, flexible electrodes to cover the application to different biosignals presented in this paper, which are electrocardiogram, electrooculogram and electromyogram. The features of this system provide to the user and to medical personnel a complete set of diagnosis tools, available both at home and hospitals, to be used as a triage tool and for remote patient monitoring. Additionally, an Android application has been developed for signal processing and data presentation to the user. The results obtained demonstrate the wide range of possibilities in portable/wearable applications of the combination of reconfigurable devices and flexible electronics, especially for the remote monitoring of patients using multiple biosignals of interest. The versatility of this device makes it a complete set of monitoring tools integrated in a reduced size device.
