PROJECT TITLE :

Wireless Fidelity Electromagnetic Field Exposure Monitoring With Wearable Body Sensor Networks

ABSTRACT:

With the breakthrough of the Internet of Things and also the steady increase of wireless applications in the daily environment, the assessment of radio frequency electromagnetic field (RF-EMF) exposure is vital in determining possible health effects of exposure to sure levels of RF-EMF. This paper presents the primary experimental validation of a novel personal exposimeter system primarily based on a distributed measurement approach to attain higher measurement quality and lower measurement variability than the commonly used single point measurement approach of existing exposimeters. An vital feature of the system is the combination of inertial sensors so as to work out activity and posture during exposure measurements. The system is intended to assess exposure to frequencies among the 389 to 464, 779 to 928 and 2400 to 2483.5 MHz bands using only 2 transceivers per node. In this study, the 240zero to 2483.five MHz band is validated. Each node provides antenna diversity for the different bands in order to achieve higher sensitivity at these frequencies. Two AAA batteries power each standalone node and as such determine the node hardware size of this proof of concept (fifty three mm×25 mm×fifteen mm), creating it smaller than any other commercially available exposimeter.
