Fully automated biosignal acquisition in daily routine through 1 month

With the goal of keeping people healthy and active, long-term at-home measurement of physiological function during daily life is valuable, and is attempted in this study. As a first trial of at-home measurements, a fully automated physiological data acquisition system was developed. This system contains unconstrained physiological parameter monitors: an ECG monitor for use during bathing, a bed temperature monitor, and a weight monitor located in the toilet seat. It also contains a computer with data acquisition programs and a data format rule. Unconstrained physiological parameter monitors and fully automatic measurement procedures provide data acquisition non-invasively and without the subject´s awareness. This system has been proved by an experiment involving measurement over one month of a healthy male subject (aged 29 years) in laboratory-based facilities. The system functioned for one month of data acquisition with no operator involved. The system may be used for home health monitoring of patients and also of healthy subjects
