Project Description

Obesity is a medical condition associated with multiple health problems. Multiple clinical guidelines about the identification, evaluation and treatment of overweight and obesity and its related risks already exist.  Importantly, these guidelines recommend the use of long-term monitoring systems that have not been adapted yet to the screening of large-scale populations to efficiently and simultaneously evaluate different physiological markers such as energy expenditure, hypertension, respiratory rate, stroke volume, heart rate and rhythm, etc. Indeed, physiological monitoring systems, if available, present multiple limitations, i.e. invasiveness, poor patient compliance, long-term skin intolerance, non-portable, limited power autonomy and memory, single-physiological marker oriented, sensitivity to motion artifacts, inaccurate estimates, etc.
