This paper describes the process of acquiring, processing and interpreting biomedical data gathered using a mobile telemedical device. The device utilizes a piezoelectric-quartz sensor for heart sound analysis, three lead ECG monitor, and accelerometer and a gyroscope. The device prototype proved to provide sufficient quality signal to be used as a heart monitor. During testing, the patient first...
Practical usability of the majority of current wearable body sensor systems for multiple parameter physiological signal acquisition is limited by the multiple physical connections between sensors and the data-acquisition modules. In order to improve the user comfort and enable the use of these types of systems on active mobile subjects, we propose a wireless body sensor system that incorporates multiple...
Optimizing performance of wireless sensor networks leads to trade-offs between local computation and communication. With the usage of on-node processing, the lifetime of the sensor nodes can be extended as raw data does not need to be sent out and logged by an external device. In this paper we present our approach for on-node processing of ECG signals to signal abnormal heart rate conditions. We develop...
Recent miniaturization of ECG sensors and other health monitoring systems potentially allowing remote monitoring of certain diseases in the patients own home. Exploiting the full potential of this technology poses several design challenges for both the miniaturized ECG sensor, as well as the required infrastructure for data transport, storage and diagnosis. This paper proposes an ECG sensor prototype...
