Physiological signals acquisition and wireless transmission :-enabling intelligent wireless sensors

摘要

In this paper we present an innovative monitoring system, that has been developed by applying new advances in wireless intelligent sensors and wireless teclinologies(PAN). Intelligent wireless sensors perform data acquisition and limited processing. Individual sensors monitor specific physiological signals (such as EEG, ECG, GSR etc.) and communicate with each other and the personal server. Personal server integrates information from different sensors and communicates with the rest of telemedical system as a standard mobile unit. A prototype implementation of Wireless Intelligent Sensor (WISE) based on a very low power consumption microcontroller and a DSP-based personal server. In future we expect all components of WISE integrated in a single chip for use in a variety of new medical applications and sophisticated human computer interfaces. Existing growth of wireless infrastructure will allow a range of new telemedical applications that will significantly improve the quality of health care.
