Low-cost Remote Monitoring of Biomedical Signals

The great usefulness of remote recording of biomedical signals in most aspects of daily life has generated an increasing interest in this field. Traditionally, monitoring devices from clinical enviroments are bulky, intrusive, and expensive. Thus, the development of wearable, mobile, and low-cost applications is desirable. Nevertheless, recent improvements in open-hardware allow developing low cost devices and portable designs for biosignal monitoring in out-of-lab applications, such as sports, leisure, e-Health, etc. This paper presents a low-cost wearable system able to simultaneously record electrical brain and heart activity (i.e. electroencephalography and electrocardiography). The system is able to send biomedical data to a platform for remote analyses. Both software and hardware are open-source. We assessed the system for its validity and reliability in a real road environment.
