Wearable wireless multi-parameter sensor module for physiological monitoring

Abstract

Advances in low power technology have given new possibilities for continuous physiological monitoring in several domains such as health care with disease prevention and quality of care services and workers in harsh environment. A miniaturized, multifunctional sensor module that transmits sensor data wirelessly using Bluetooth Smart technology has been developed. The wireless communication link is influenced by factors like antenna orientation, reflections, interference and noise. Test results for signal strength measurements for the wireless transmission in various setups are given and discussed.
