In this population, WCH is very common and benign. HBP monitoring is feasible and well accepted. However, teletransmission is necessary for safety.

The prototype of a communicating underclothe for medical remote monitoring was realized. It delivers physiological information on the subject (Cardiac Frequency, Breathing Frequency, surface and mid-temperature) as well as the environment and activity parameters (ambient temperature, fall detection). It also enables the automatic data transfer on event, with the localization of the subject.

Healthcare monitoring is a general concern for patients requiring a continuous medical assistance and treatment. In order to increase mobility of such patients, a huge effort is pursued worldwide for the development of wearable monitoring systems able to measure vital physiological parameters such as respiratory movements, cardiac activity, pulse oximetry, temperature of the body [1]. Technical or smart textiles that incorporate different sensors play a growing role in these developments as they are well suited for wearability and can ensure comfort to the user [2, 3]. While most developments up to now have been focused on the use of electrical sensors, the aim of OFSETH [4] is to take advantage of pure optical sensing technologies for extending the capabilities of medical technical textiles for wearable health monitoring. OFSETH expects to achieve a breakthrough in healthcare monitoring applications where standard (non-optical) monitoring techniques show significant limits such as for the monitoring of anesthetized patients under Medical Resonance Imaging (MRI).

We report on the results of clinical evaluation of a newly developed system for wireless monitoring of pulse oximetry (SpO2), actimetry and position in infants. The sensors, electronics and the power supply were integrated into a specially designed infant shoe named BBA bootee. The comparative data collected in 71 babies yielded a mean (bias +/- SD) value of (-1.2 +/- 1.9) % for SpO2 and (-2 +/- 8) beats per minute for heart rate with regard to reference monitors. A reliable detection of infant's movements and prone position by an integrated 3-axes accelerometer has been validated by video observations. Combining the pulse oximetry and actimetry data, an algorithm is proposed to reduce the oximetry motion artifact and related false alarms. Ergonomics of the sensor-supporting garment is addressed.

The prototype of a communicating undercloth for medical remote monitoring was realized. It delivers physiological information on the subject (Cardiac Frequency, Breathing Frequency, mid-temperature) as well as the environment and activity parameters (ambient temperature, fall detection). It also enables the automatic data transfer when an event occurs, with the localization of the subject.
