Biosignal analysis implemented on state of the art smartphone dual-core processors

Monitoring vital signs is one of the most crucial components of modern health care, however does not require a full fletched desktop computer any more. Instead, the steady increase in computing power, visible with smart phones, enables signal processing and monitoring algorithms to be executed on embedded devices. As such a truly 24/7 personal health monitoring with local alarm capabilities, but wireless data transmission is the goal of the work presented here. As conceptual proof, a vital signs monitor was developed and tested in animal experiments, which started at the push of one button to transmit multiple channel biosignals to a host PC by WLAN and at the same time pre-analysing ECG signals for extrema in the heart rate.
