- Brief Summary
Body temperature is one of the markers of biological rhythms. The precise determination of the functioning of the biological clock for an individual is essential to understanding his physiological state at a given time. This condition is dependent on the "timing" of its central clock on the time scale (chronotype). The provision of a simple-to-use (F2D cuff), non-invasive and time-dependable temperature tool and the creation of appropriate algorithms would allow access to the operation of the central clock and open up many therapeutic applications.
- Detailed Description
While the measurement of body temperature is one of the first self-diagnosis gestures at home, it is unanimously agreed by healthcare professionals that the measurement of non-invasive body temperature performed both in a hospital setting, in the office, that at home is very imprecise, or even false. As a result, temperature is only an indicator and is of little interest. Only the rectal thermometer and the telemetric capsule (e-CELSIUS® capsule to be ingested that allows a reliable and continuous measurement of gastrointestinal temperature without the intervention of the caregiver) are reliable tools, but they remain invasive and do not always allow for fully reliable follow-up over time. We propose to develop an algorithm integrated in an external, non-invasive cuff, allowing the continuous recording of body temperature.
In addition, body temperature is one of the markers of biological rhythms. The precise determination of the functioning of the biological clock for an individual is essential to understanding his physiological state at a given time. This condition is dependent on the "timing" of its central clock on the time scale (chronotype). The provision of a simple-to-use (F2D cuff), non-invasive and time-dependable temperature tool and the creation of appropriate algorithms would allow access to the operation of the central clock and open up many therapeutic applications.
This work proposes to validate the tool on the one hand and on the other to use this tool to produce the elements necessary for monitoring the functioning of the central biological clock.

Group Intervention Description Observational F2D armband Comparison of the core temperature obtained during 24-48 h with eCelsius and with F2D armband in different life situations.
- Primary Outcome Measures
Name Time Method WP1 (body temperature) 24 hours Comparison of the body temperature obtained by the e-CELSIUS® system with the body temperature obtained with the F2D system in 2 situations : during an exercice, to rise the core temperature, and during a nap taken in the afternoon to reduce it.
WP2 (body temperature) 48 hours To continuously record the internal and external body temperature obtained with the e-CELSIUS® system and the F2D cuff for 48 hours to obtain a corpus of data allowing algorithm productions being able to quantify and qualify the circadian rhythmicity and determine the chronotype of normo-weighted subjects.
WP3 (body temperature) 48 hours To continuously record the internal and external body temperature obtained with the e-CELSIUS® system and the F2D cuff for 48 hours to obtain a corpus of data allowing algorithm productions being able to quantify and qualify the circadian rhythmicity and determine the chronotype of subjects with varying ages and body sizes .
