Full title: Compact antennas for biomedical applications
Duration: Jun. 2014 – Jun. 2017
Role: Coordinator at IETR
Short description:
This research collaboration with BodyCap Medical Company aims at the design, optimization, and integration of miniature antenna structures for biomedical applications. The company specializes in wearable connected devices for physiological data monitoring, its innovative high-tech products are used in medical, research, and sport/ergonomics areas. The main focus of the research is to extend the efficiency and robustness of antennas for in-body and cutaneous devices whereas reducing the volume occupied by the antenna in a device.

Short description:
Recently, the millimeter-wave band, mainly 57-66 GHz range, has been identified as highly promising for future body-area network (BAN) technologies. One of the main features differentiating the 60-GHz band from lower frequency BAN is confidentiality and low interference level with neighboring networks, which has been demonstrated to be crucial for body-centric and inter-BAN communications. In addition, it provides other advantages including high data rates [typically beyond 5 Gb/s], reduced size of antennas and sensors, high accuracy for localization, that can be exploited for new applications. The ResCor project focused on exploration of antenna solutions in the 60-GHz BAN in the near-field region since this corresponds to the most relevant user scenario for most of the BAN and inter-BAN applications. It also dealt with development of novel solid body models in the 60-GHz band and investigation of the on-nody propagation channel.

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.
