Abstract

The low-power sensing platform proposed by the Convergence project is foreseen as a wireless, low-power and multifunctional wearable system empowered by energy-efficient technologies. This will allow meeting the strict demands of life-style and healthcare applications in terms of autonomy for quasi-continuous collection of data for early-detection strategies. The system is compatible with different kinds of sensors, able to monitor not only health indicators of individual person (physical activity, core body temperature and biomarkers) but also the environment with chemical composition of the ambient air (NOx, COx, NHx particles) returning meaningful information on his/her exposure to dangerous (safety) or pollutant agents. In this article, we introduce the specifications and the design of the low-power sensing platform and the different sensors developed in the project, with a particular focus on pollutant sensing capabilities and specifically on NO2 sensor based on graphene and CO sensor based on polyaniline ink.

Highlights

The importance and emergence of the Internet-of-Things and connected devices, led us to develop new efficient solutions for preventive healthcare, environment and life-style [1,2].In that context, the development of wearable platforms embedding bio and environment sensors is of high importance to enable personalized advices and assistance for health and interactions with the environment

Summary

Introduction

The development of wearable platforms embedding bio and environment sensors is of high importance to enable personalized advices and assistance for health and interactions with the environment. The latter, when degraded by the presence of anthropogenic and natural pollutants, is widely recognized as the most effective driver of severe health conditions. The purpose of the Convergence project is to develop and demonstrate a low-power wearable platform dedicated to monitoring by exploiting the convergence of multi-parameter devices such as bio-, activity and environmental sensors. A multi-sensors platform was designed for the acquisition of individual physical condition parameters (physical activity, core body temperature, sweat and pH) and the chemical composition of the surrounding ambient air (NOx , COx , NHx compounds)
