Full title: Characterization of exposures induced by emerging wireless power transfer systems

Duration: Dec. 2013 – Jul. 2017

Funded by: French Agency for Food, Environmental and Occupational Health and Safety (ANSES)

Role: Coordinator

Short description:

The main purpose of the project is to characterize numerically and experimentally exposures induced by emerging wireless power transfer (WPT) systems, considered as the last missing element for the ubiquitous mobility. WPT systems will operate relatively high powers (from Watts to MWatts depending on the application and operating range).  The main objectives of the ExpoWPT project are twofold:

1) Dosimetric assessment of the exposure levels induced in the human body by representative WPT exposure scenarios, including those involving the individuals with implants.

2) Design and characterization of a new exposure system reproducing the EM field induced by representative WPT systems. This exposure system will be used to assess potential biological impacts at the cellular level.

Full title: Exposure system based on a millimeter-wave reverberating chamber

Duration: Dec. 2014 – Jul. 2017

Funded by: French Agency for Food, Environmental and Occupational Health and Safety (ANSES)

Role: In charge of dosimetry.

Short description:

Wireless communication systems in the millimeter-wave range, in particular around 60 GHz, are expected to to be largely deployed in coming years for short-range high-data-rate transmissions. The available information regarding user exposure in this band is limited due to lack of commercially available dosimetric instrumentation, particularly for in vivo testing. The CREOM project aims at design and fabrication of a new experimental tool based on a millimeter-wave reverberation chamber.

Full title: Investigation of millimeter wave effects on cellular systems using a metabolomic approach

Duration: Dec. 2014 – Jul. 2017

Funded by: French Agency for Food, Environmental and Occupational Health and Safety (ANSES)

Role: Participant

Short description:

The main objective of the BEMAM project is to investigate potential biological effects of millimeter-wave radiations on cells using a metabolomic approach. This project brings together experts in cellular and molecular biology, chemical analysis, and electromagnetics. We employ the high resolution mass spectrometry interfaced with liquid chromatography to simultaneously measure hundreds of metabolites (small molecules whose chemical structure is related to the cell metabolism) as a functional readout of the cellular state.

Full title: Millimeter waves and nerve cells

Duration: Dec. 2012 – Dec. 2015

Funded by: French Agency for Food, Environmental and Occupational Health and Safety (ANSES)

Role: in charge of the antenna design and dosimetry part of the project

Short description:

The project dealt with the study of possible modifications at the cellular level (neuron-like cellular model) after exposure at millimeter waves under near-field conditions using cell-to-cell analysis. As a part of the project, we focused on development of specific near-field exposure and multi-physics dosimetry tools in an anechoic environment.

Full title: Metamaterials for intelligent clothing

Duration: Nov. 2009 – Apr. 2013

Funded by: French National Research Agency (ANR)

Role: in charge of the “antenna / human body interaction” part of the project

Short description:

Over the last few years, our clothing has become more comfortable and lighter, thanks to new synthetic fibres, but another technological revolution has started – they are becoming communicating and even… caring! Thanks to recent progress in design of intelligent networks and miniaturization techniques of communicating objects wireless networks in the vicinity of a person are today attracting increasing attention due to the large range of potential applications. On-body sensors are already widespread and they may be integrated into textiles, with the concept of “smart clothing ” that can convey a wide range of information (communications, localization, RFID, monitoring of vital physiological parameters, management of urgency situation, etc.). All these applications justify the growing interest to this technology. Study of body-centric propagation implies the characterization and modelling of electromagnetic properties of various biological tissues.  The METAVEST project dealt with the study textile antennas to be integrated in clothing (WPAN and DVB-H bands) and reduction of the antenna / human body coupling.
