Monitoring of active physiological parameters without radio waves

Abstract

The aging of the world population is leading to an increase in diseases, aggravating the frailty and therefore reducing the autonomy of the elderly. Wireless body sensor networks are one of the solutions studied for several years to monitor and thus prevent the health disabilities of the elderly. Most of the existing devices offer wireless communications based on radio frequency (RF) technologies. However, electromagnetic interference and the health risks of radio waves constitute a brake on deployment. Thus, an original alternative in this context is the use of wireless optical communication technologies.The Sycomor team of the XLIM laboratory has been working for several years on this technology, in particular on channel modeling and performance evaluation for body area networks. Several collaborations on the subject have been established : with the HAVAE laboratory of University of Limoges, Limoges University Hospital Center, University Partnership Foundation and CISTEME, the technology transfer center close to laboratory concerns. Among the applications, we focus on environments where radio waves are not recommended, mainly for health reasons or regarding security of the transmitted information. Particularly, in the context of young children or for people wearing implanted electronic devices, radio waves are not suitable. Thus, the work carried out by the team covers both the supervision of the young child and that of the elderly or fragile person.
