Abstract:

Every day, the number of connected sensors keeps increasing and 24 billion Internet of Things are expected to be available by 2020. These sensors cover a wide number of domains, from home automation to improving companies’ productivity, and todays IoT is connecting every aspect in our life. Health is also concerned by IoT and healthcare market is estimated to be around 410 million
dollars by 2022. Manufacturers are developing all kinds of sensors such as blood pressure monitor, pulse oximeter, weigh scale, actimeter, glucose meter... This diversity of sensors allows a reliable health monitoring, either for prevention or for diagnosis and treatment. With medical progress, life expectancy increased from 77.7 in 2002 to 80.6 in 2013 in the European Union. Furthermore, elders will represent 30% of the French population by 2060, that is to say 20 million people.
As the same time as life expectancy is growing, an increasing number of persons are prevented from accessing medical healthcare due to its costs. Therefore, a new P4-medicine, i.e. preventive, predictive, personalized and participatory, is emerging helping in health prevention. This specific medicine becomes possible by means of the increasing number of IoT and the quantified self movement.
Silver@Home is a telemonitoring solution we are developing including a fall detection sensor and a set of connected sensors to accompany elders in their health care, not only at home but also outdoors. This solution, facing challenges, such as interoperability, reliability, multimodality, mainly focuses on the motivational aspect in order to make elders participate in their personal health. It uses a set of medical and/or wellness sensors for data acquisition and processing to qualify/quantify user's health status. Measures are sent to an authorized system for hosting personal health data, ensuring a high level of security, ethical, technical and economical requirements to secure medical
data. A specific administration of the French Ministry of health, named ASIP Santé (Agence des Systèmes d’Information Partagés de Santé) delivers this authorization. Results are communicated to the elder himself and eventually to his family or a medical team depending on his desire.
