Abstract

With the breakthrough of the Internet of Things and the steady increase of wireless applications in the daily environment, the assessment of radio frequency electromagnetic field (RF-EMF) exposure is key in determining possible health effects of exposure to certain levels of RF-EMF. This paper presents the first experimental validation of a novel personal exposimeter system based on a distributed measurement approach to achieve higher measurement quality and lower measurement variability than the commonly used single point measurement approach of existing exposimeters. An important feature of the system is the integration of inertial sensors in order to determine activity and posture during exposure measurements. The system is designed to assess exposure to frequencies within the 389 to 464, 779 to 928 and 2400 to 2483.5 MHz bands using only two transceivers per node. In this study, the 2400 to 2483.5 MHz band is validated. Every 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 (53 mm×25 mm×15 mm) , making it smaller than any other commercially available exposimeter.

Main findings

The paper reports an experimental validation of a novel distributed personal exposimeter system intended to provide higher measurement quality and lower measurement variability than single-point exposimeters. In this study, the 2400 to 2483.5 MHz band was validated, and the proof-of-concept node size is reported as 53 mm×25 mm×15 mm.

Outcomes measured

  • Performance/validation of a wearable personal exposimeter system for RF-EMF exposure monitoring
  • Measurement quality and variability compared with single-point exposimeters
  • Ability to assess activity and posture during exposure measurements (via inertial sensors)

Limitations

  • Only the 2400 to 2483.5 MHz band was validated in this study (other designed bands not validated here).
  • No health outcomes are reported; the work focuses on exposure monitoring/measurement system validation.
  • Sample size and validation protocol details are not provided in the abstract.
